Media Sync

• Auto Sync
  • When a hard drive is connected (one allowed by usbguard), run an application
  • Using an /etc config file, the UUID maps to what type of content to sync
  • rsync the type of content to the mount point of the hard drive
  • in the background, regularly check the progress of the transfer (du -sbc /dst | tail -1 | cut -f1) / (du -sbc /src | tail -1 | cut -f1) and write the percentage to /tmp/media/mount_point
    • if the size > 100, flip the division
    • if rsync is not running, empty /tmp/media/mount_point
    • if the media is not mounted, remove /tmp/media/mount_point
• Kiosk
  • systemd start startx
  • systemd start xprogress
  • systemd start chromium --kiosk
  • run autologin startx on tty1 on boot
  • exec chromium-browser --kiosk
  • on x11 app exit, exit the tty and restart
  • can switch to another terminal to do a normal login
• Setup
  • app.rpm
    • sig.rpm
  • kiosk.rpm
    • xorg.rpm
    • xprogress.rpm
    • chromium.rpm
    • startx systemd
    • xprogress systemd
    • chromium systemd
    • nic configuration

"Plan B"

• while :; do if [ tty == 5 ]; then chvt 6; else chvt 6; fi; sleep 60; done
• Progress Meter
  • $ ((i=0)); while :; do sleep .01; perl -E '$=sprintf "%.2f", ($ARGV[0]/$ARGV[1])*100; say "$%"; exit ($_<100)' $((i++)).$RANDOM 100 && break; done | zenity --progress --no-cancel --auto-close --text="Syncing to /media" --title="Busy"
  • $ while :; do sleep .01; perl -E 'exit 0 unless $ARGV[1]; $=sprintf "%.2f", ($ARGV[0]/$ARGV[1])*100; say "$%"; exit ($_<100)' "$(du -sbc /opt | tail -1 | cut -f1)" "$(du -sbc /opt | tail -1 | cut -f1)" && break; done | zenity --progress --no-cancel --auto-close --text="Syncing to /media" --title="Busy"
  • can root process run zenity on another xsession? or will user xinitrc need to run a background process that is always monitoring rsync?
