Hi,
I recently replaced the SSD drive in my laptop and the new one turned out to be
using completely different technology (namely nvme as opposed to sata).
It costed me a lot of fuss to make my system able to boot up from the new drive
(ie. I did a fresh installation of Qubes just to realise it put the necessary
nvme driver into initramfs, the lack of which on my original OS had been the
cause of the issue).
My question is: how can I add necessary drivers to initramfs
(/boot/efi/EFI/qubes/initramfs-*)? For instance, referring to the scenario
above, I would like to add nvme kernel modules to initramfs to be able to boot
the system when I move it to the new drive.
I don't have a UEFI setup to test but the following should work:
mkinitrd --with=yourmodule /path/to/new/initramfs $(uname -r)
(see `man mkinitrd` ; mkinitrd is actually frontend to dracut).
IIRC, you can specify multiple modules with several `--with=` options.
Backup your current initramfs if you use the same filename as you
current initramfs (eg., "/initramfs-4.14.67-1.pvops.qubes.x86_64.img").
Or alternatively, use a different filename and tweak the config at boot
time in grub when testing, and then overwrite the old initramfs with the
new one once everything works as expected.
