Thanks for working on this!
Few additional comments:
Should we now also change linux-grsec and linux-vanilla to not depend
on linux-firmware? Because they still pull in the meta-package pulling
in everything. Should the modules be split accordingly? Or should we
pull in some core firmwares only automatically?
Btw. mkinitfs properly picks up the firmwares for initramfs disks based
on kernel modules on initramfs. See:
I earlier had the idea to do similar pruning for linux-firmware package
as it contains overlapping versions of firmwares, and firmwares for
modules we don't even build. However, this would require us to track the
firmwares requires for all of the kernel builds we do (all arches; all
configs). So it was not so trivial to implement.
And finally a minor nitpick: now have linux-firmware-RTL8192E;
generally we don't use uppercase in package names.
But thanks again for working on this. I have had on my todo list for a
while and good to see you're getting it done :)
