    ## Required

    #### Hardware
    - TPM module installed in the motherboard (that is set to TPM 2.0 mode from the BIOS).

    #### Packages
    - refind
    - sbsigntools
    - shim-signed
    - tpm2-tss-engine
    - tpm2-tools (optional)

    Archlinux / Manjaro: `pamac update --download-only --aur && pamac install refind sbsigntools shim-signed tpm2-tss-engine`

    ## Usage

    ```bash
    sudo -i

    # Patch refind-install script
    curl -o- https://gist.githubusercontent.com/heri16/6df9ae37ae51496fe376debaca45540b/raw/refind-install.patch | patch /usr/bin/refind-install

    # Install reFind EFI Bootloader to ESP partition (encrypted keys without TPM)
    # refind-install --shim /usr/share/shim-signed/shimx64.efi --localkeys --encryptkeys --yes

    # Install reFind EFI Bootloader to ESP partition (encrypted keys on TPM)
    refind-install --shim /usr/share/shim-signed/shimx64.efi --localkeys --encryptkeys --engine tpm2tss --yes
    efibootmgr

    # Sign Linux kernel
    sbsign --engine tpm2tss --key /etc/refind.d/keys/refind_local.key --cert /etc/refind.d/keys/refind_local.crt --output "/boot/vmlinuz-5.6-x86_64" "/boot/vmlinuz-5.6-x86_64"
    sbverify --list "/boot/vmlinuz-5.6-x86_64"

    # Sign Manjaro's Grub2 EFI Bootloader (optional)
    sbsign --engine tpm2tss --key /etc/refind.d/keys/refind_local.key --cert /etc/refind.d/keys/refind_local.crt --output "/boot/efi/EFI/manjaro/grubx64.efi" "/boot/efi/EFI/manjaro/grubx64.efi"
    sbverify --list "/boot/efi/EFI/manjaro/grubx64.efi"

    # Reboot into BIOS
    ```

    Then, reboot into BIOS to enable SecureBoot.

    Once in **MokManager** add `refind_local.cer` to MoKList. `refind_local.cer` can be found inside a directory called keys in the rEFInd's installation directory, e.g. `esp/EFI/refind/keys/refind_local.cer`.

    # Linux/MacOS X script to install rEFInd
    #
    # Usage:
    #
    # ./refind-install [options]
    #
    # options include:
    # "--notesp" to install to the OS X root filesystem rather than to the ESP.
    # This option is valid only under OS X.
    # "--usedefault {devicefile}" to install as default
    # (/EFI/BOOT/BOOTX64.EFI and similar) to the specified device
    # (/dev/sdd1 or whatever) without registering with the NVRAM.
    # "--ownhfs {devicefile}" to install to an HFS+ volume that's NOT currently
    # an OS X boot volume. Valid only in OS X.
    # "--root {dir}" to specify installation using the specified directory
    # as the system's root
    # "--alldrivers" to install all drivers along with regular files
    # "--nodrivers" to suppress driver installation (default in Linux is
    # driver used on /boot; --nodrivers is OS X default).
    # "--shim {shimfile}" to install a shim.efi file for Secure Boot. Valid
    # only under Linux.
    # "--preloader" is synonymous with "--shim". Valid only under Linux.
    # "--encryptkeys" password-protects the Secure Boot private key.
    # "--localkeys" to re-sign x86-64 binaries with a locally-generated key.
    # Valid only under Linux.
    # "--keepname" to keep refind_x64.efi name as such even when using shim.
    # Valid only under Linux.
    # "--yes" to assume a "yes" response to all prompts

    # Revision history:
    #
    # 0.12.0 -- Improve code to find ESPs; should help with NVMe drives. Also
    # activate install and bootorder features when using --usedefault
    # option.
    # 0.11.5 -- Remove excessive slashes (/) from some filenames
    # 0.11.4 -- Fixed generation of GUID when automount of ESP in use on Linux
    # 0.11.3 -- Added support for ESP mounted at /efi under Linux
    # 0.11.1 -- In Linux, be less aggressive about replacing existing NVRAM entries
    # 0.11.0 -- Create BOOT.CSV file and option to encrypt SB private key
    # 0.10.8 -- Enabled use of shimx64.efi.signed as Shim source file
    # 0.10.7 -- Added mm{arch}.efi as equivalent of MokManager.efi
    # 0.10.6 -- Improved identification of the root device under macOS.
    # 0.10.5 -- More improvement to handling of disks (other than /dev/[sh]d? disks).
    # 0.10.4 -- Improved handling of disks (other than /dev/[sh]d? disks).
    # 0.10.2 -- Improved Secure Boot detection in Linux, fixed --usedefault in OS X,
    # and fixed bug that could cause mountesp to be installed as a FILE
    # called /usr/local/bin in OS X.
    # 0.10.1 -- Improve extraction of default kernel options from /proc/cmdline.
    # Add support for AMD64 (aka AARCH64, aa64) platform. Added
    # warning when --alldrivers used without --usedefault.
    # 0.10.0 -- Enable running under OS X's recovery system & add warning about
    # SIP & brief instructions on how to deal with it if SIP is
    # detected to be enabled. Also change way refind_linux.conf default
    # options are found; use /proc/cmdline as base.
    # 0.9.2 -- Added --keepname option.

    # Shim & MokManager files over themselves; fixed bug that caused
    # inappropriate installation to EFI/BOOT/bootx64.efi
    # 0.8.6 -- Fixed bugs that caused misidentification of ESP on disks with
    # partition numbers over 10 on OS X and misidentification of mount
    # point if already-mounted ESP had space in path.
    # 0.8.5 -- Refinement/cleanup of new OS X ESP-as-default policy
    # 0.8.4 -- OS X default changed to install to ESP under /EFI/BOOT
    # 0.7.9 -- Fixed bug that caused errors if dmraid utility not installed

    # in their names
    # 0.6.9 -- Install gptsync on Macs
    # 0.6.8 -- Bug fix: ESP scan now uses "uniq".
    # 0.6.6 -- Bug fix: Upgrade drivers when installed to EFI/BOOT. Also enable
    # copying shim.efi and MokManager.efi over themselves.
    # 0.6.4 -- Copies ext2 driver rather than ext4 driver for ext2/3fs

    # 0.5.1.1 -- Fixed bug that caused script failure under OS X
    # 0.5.1 -- Added --shim & --localkeys options & create sample refind_linux.conf
    # in /boot
    # 0.5.0 -- Added --usedefault & --drivers options & changed "esp" option to "--esp"
    # 0.4.5 -- Fixed check for rEFItBlesser in OS X
    # 0.4.2 -- Added notice about BIOS-based OSes & made NVRAM changes in Linux smarter
    # 0.4.1 -- Added check for rEFItBlesser in OS X
    # 0.3.3.1 -- Fixed OS X 10.7 bug; also works as make target
    # 0.3.2.1 -- Check for presence of source files; aborts if not present
    # 0.3.2 -- Initial version
    #
    # Note: install.sh version numbers match those of the rEFInd package
    # with which they first appeared.

    # Linux/MacOS X script to install rEFInd
    #
    # Usage:
    #
    # ./refind-install [options]
    #
    # options include:
    # "--notesp" to install to the OS X root filesystem rather than to the ESP.
    # This option is valid only under OS X.
    # "--usedefault {devicefile}" to install as default
    # (/EFI/BOOT/BOOTX64.EFI and similar) to the specified device
    # (/dev/sdd1 or whatever) without registering with the NVRAM.
    # "--ownhfs {devicefile}" to install to an HFS+ volume that's NOT currently
    # an OS X boot volume. Valid only in OS X.
    # "--root {dir}" to specify installation using the specified directory
    # as the system's root
    # "--alldrivers" to install all drivers along with regular files
    # "--nodrivers" to suppress driver installation (default in Linux is
    # driver used on /boot; --nodrivers is OS X default).
    # "--shim {shimfile}" to install a shim.efi file for Secure Boot. Valid
    # only under Linux.
    # "--preloader" is synonymous with "--shim". Valid only under Linux.
    # "--encryptkeys" password-protects the Secure Boot private key.
    # "--engine" engine that protects the Secure Boot private key.
    # "--localkeys" to re-sign x86-64 binaries with a locally-generated key.
    # Valid only under Linux.
    # "--keepname" to keep refind_x64.efi name as such even when using shim.
    # Valid only under Linux.
    # "--yes" to assume a "yes" response to all prompts

    # Revision history:
    #
    # 0.12.0 -- Improve code to find ESPs; should help with NVMe drives. Also
    # activate install and bootorder features when using --usedefault
    # option.
    # 0.11.5 -- Remove excessive slashes (/) from some filenames
    # 0.11.4 -- Fixed generation of GUID when automount of ESP in use on Linux
    # 0.11.3 -- Added support for ESP mounted at /efi under Linux
    # 0.11.1 -- In Linux, be less aggressive about replacing existing NVRAM entries
    # 0.11.0 -- Create BOOT.CSV file and option to encrypt SB private key
    # 0.10.8 -- Enabled use of shimx64.efi.signed as Shim source file
    # 0.10.7 -- Added mm{arch}.efi as equivalent of MokManager.efi
    # 0.10.6 -- Improved identification of the root device under macOS.
    # 0.10.5 -- More improvement to handling of disks (other than /dev/[sh]d? disks).
    # 0.10.4 -- Improved handling of disks (other than /dev/[sh]d? disks).
    # 0.10.2 -- Improved Secure Boot detection in Linux, fixed --usedefault in OS X,
    # and fixed bug that could cause mountesp to be installed as a FILE
    # called /usr/local/bin in OS X.
    # 0.10.1 -- Improve extraction of default kernel options from /proc/cmdline.
    # Add support for AMD64 (aka AARCH64, aa64) platform. Added
    # warning when --alldrivers used without --usedefault.

    # Linux/MacOS X script to install rEFInd
    #
    # Usage:
    #
    # ./refind-install [options]
    #
    # options include:
    # "--notesp" to install to the OS X root filesystem rather than to the ESP.
    # This option is valid only under OS X.
    # "--usedefault {devicefile}" to install as default
    # (/EFI/BOOT/BOOTX64.EFI and similar) to the specified device
    # (/dev/sdd1 or whatever) without registering with the NVRAM.
    # "--ownhfs {devicefile}" to install to an HFS+ volume that's NOT currently
    # an OS X boot volume. Valid only in OS X.
    # "--root {dir}" to specify installation using the specified directory
    # as the system's root
    # "--alldrivers" to install all drivers along with regular files
    # "--nodrivers" to suppress driver installation (default in Linux is
    # driver used on /boot; --nodrivers is OS X default).
    # "--shim {shimfile}" to install a shim.efi file for Secure Boot. Valid
    # only under Linux.
    # "--preloader" is synonymous with "--shim". Valid only under Linux.
    # "--encryptkeys" password-protects the Secure Boot private key.
    # "--localkeys" to re-sign x86-64 binaries with a locally-generated key.
    # Valid only under Linux.
    # "--keepname" to keep refind_x64.efi name as such even when using shim.
    # Valid only under Linux.
    # "--yes" to assume a "yes" response to all prompts

    # Revision history:
    #
    # 0.12.0 -- Improve code to find ESPs; should help with NVMe drives. Also
    # activate install and bootorder features when using --usedefault
    # option.
    # 0.11.5 -- Remove excessive slashes (/) from some filenames

    # Linux/MacOS X script to install rEFInd
    #
    # Usage:
    #
    # ./refind-install [options]
    #
    # options include:
    # "--notesp" to install to the OS X root filesystem rather than to the ESP.
    # This option is valid only under OS X.
    # "--usedefault {devicefile}" to install as default
    # (/EFI/BOOT/BOOTX64.EFI and similar) to the specified device
    # (/dev/sdd1 or whatever) without registering with the NVRAM.
    # "--ownhfs {devicefile}" to install to an HFS+ volume that's NOT currently
    # an OS X boot volume. Valid only in OS X.
    # "--root {dir}" to specify installation using the specified directory
    # as the system's root
    # "--alldrivers" to install all drivers along with regular files
    # "--nodrivers" to suppress driver installation (default in Linux is
    # driver used on /boot; --nodrivers is OS X default).
    # "--shim {shimfile}" to install a shim.efi file for Secure Boot. Valid
    # only under Linux.
    # "--preloader" is synonymous with "--shim". Valid only under Linux.
    # "--encryptkeys" password-protects the Secure Boot private key.
    # "--engine" engine that protects the Secure Boot private key.
    # "--localkeys" to re-sign x86-64 binaries with a locally-generated key.
    # Valid only under Linux.
    # "--keepname" to keep refind_x64.efi name as such even when using shim.
    # Valid only under Linux.
    # "--yes" to assume a "yes" response to all prompts

    # Revision history:
    #
    # 0.12.0 -- Improve code to find ESPs; should help with NVMe drives. Also
    # activate install and bootorder features when using --usedefault
    # option.
    # 0.11.5 -- Remove excessive slashes (/) from some filenames
    # 0.11.4 -- Fixed generation of GUID when automount of ESP in use on Linux
    # 0.11.3 -- Added support for ESP mounted at /efi under Linux
    # 0.11.1 -- In Linux, be less aggressive about replacing existing NVRAM entries
    # 0.11.0 -- Create BOOT.CSV file and option to encrypt SB private key
    # 0.10.8 -- Enabled use of shimx64.efi.signed as Shim source file
    # 0.10.7 -- Added mm{arch}.efi as equivalent of MokManager.efi
    # 0.10.6 -- Improved identification of the root device under macOS.
    # 0.10.5 -- More improvement to handling of disks (other than /dev/[sh]d? disks).
    # 0.10.4 -- Improved handling of disks (other than /dev/[sh]d? disks).
    # 0.10.2 -- Improved Secure Boot detection in Linux, fixed --usedefault in OS X,
    # and fixed bug that could cause mountesp to be installed as a FILE
    # called /usr/local/bin in OS X.
    # 0.10.1 -- Improve extraction of default kernel options from /proc/cmdline.
    # Add support for AMD64 (aka AARCH64, aa64) platform. Added
    # warning when --alldrivers used without --usedefault.
    # 0.10.0 -- Enable running under OS X's recovery system & add warning about
    # SIP & brief instructions on how to deal with it if SIP is
    # detected to be enabled. Also change way refind_linux.conf default
    # options are found; use /proc/cmdline as base.
    # 0.9.2 -- Added --keepname option.
    # 0.8.7 -- Better detection of Secure Boot mode & fixed errors when copying
    # Shim & MokManager files over themselves; fixed bug that caused
    # inappropriate installation to EFI/BOOT/bootx64.efi
    # 0.8.6 -- Fixed bugs that caused misidentification of ESP on disks with
    # partition numbers over 10 on OS X and misidentification of mount
    # point if already-mounted ESP had space in path.
    # 0.8.5 -- Refinement/cleanup of new OS X ESP-as-default policy
    # 0.8.4 -- OS X default changed to install to ESP under /EFI/BOOT
    # 0.7.9 -- Fixed bug that caused errors if dmraid utility not installed
    # 0.7.7 -- Fixed bug that created mangled refind_linux.conf file; added ability
    # to locate and mount ESP on Linux, if it's not mounted
    # 0.7.6 -- Added --ownhfs {device-filename} option
    # 0.7.5 -- Fixed bug when installing to ESP on recent versions of OS X
    # 0.7.2 -- Fixed code that could be confused by use of autofs to mount the ESP
    # 0.7.0 -- Added support for the new Btrfs driver
    # 0.6.12 -- Added support for PreLoader as well as for shim
    # 0.6.11 -- Improvements in script's ability to handle directories with spaces
    # in their names
    # 0.6.9 -- Install gptsync on Macs
    # 0.6.8 -- Bug fix: ESP scan now uses "uniq".
    # 0.6.6 -- Bug fix: Upgrade drivers when installed to EFI/BOOT. Also enable
    # copying shim.efi and MokManager.efi over themselves.
    # 0.6.4 -- Copies ext2 driver rather than ext4 driver for ext2/3fs
