Linux Kernel Firmware Packages

Motivation

Kernel firmware packages consume a lot of disk space on a Linux system, both on the installed system and in an installation environment (inst-sys). In some cases (e.g. RAM disk for a minimal NET ISO), that also means a lot of RAM usage.

The workaround for this was to set LD_PRELOAD if libsuseconnect.so was
found, but that causes new problems: This is inherited by child
processes, and now every binary started from YaST also gets this
LD_PRELOAD, so they are now also force linked to libsuseconnect.so.

YaST uses external programs extensively; among lots of other things,
for storage probing. That means that in many cases, storage probing
now fails because of this; mostly due to out of memory because
libsuseconnect.so (and the Go runtime libs that it uses?) consumes a
lot more RAM.
