During installation, /usr/lib/kernel/install.d/50-dracut.install
generate initramfs in $BOOT_DIR_ABS. It is important to use that one,
even if there is one in /boot/initramfs-*.img already, because it was
generated later and contains all required config files (including
keyboard layout for entering LUKS passphrase).
This fixes d1f3be0eed "kernel-install:
avoid creating initramfs multiple times".
FixesQubesOS/qubes-issues#3234
(cherry picked from commit bcf7c9e978)
There are multiple places where initramfs can be created:
- /boot/iniramfs-*.img
- /boot/$MACHINE_ID/.../initrd (unused on Qubes, but created by Fedora
scripts)
- /boot/efi/EFI/.../initramfs-*.img
Do not generate all of those from scratch, but try to reuse existing
image (if exists). Since one dracut call may last even 5 minutes, this
change should greatly reduce installation time.

I need to set some flags in order to boot as described here:
https://www.qubes-os.org/doc/uefi-troubleshooting/
My settings look like this:
$ efibootmgr -v
BootCurrent: 0000
Boot0000* Qubes HD(...)/File(\EFI\qubes\xen.efi)p.l.a.c.e.h.o...
which causes awk to get confused and think my $EFI_DIR should be:
/EFI/qubesp.l.a.c.e.h.o.l.d.e.r. ./.m.a.p.b.s. ./.n.o.e.x.i.t.b.o.o.t.
This causes the script to later bail:
if [ ! -d "$EFI_DIR" ]; then
# non-EFI system
exit 0;
fi
So my xen.cfg did not get new entries when installing dom0 kernel packages.
The entry may be already present for example when reinstalling package,
or calling the script multiple times (which apparently is the case
during system installation).
In non-EFI installation /boot/efi/EFI/qubes may not exists. In this case
do not try to touch (non-existing) files there.
FixesQubesOS/qubes-issues#1829
The specification doesn't cover how to boot Xen (or any other multiboot
binary), but the sole presence of such directory changes dracut default
path. So get rid of that directory.
Since we now allow using Fedora kernel, add a script to generate proper
bootloader configuration then. Standard Fedora mechanism relies on
Boot Loader Specification support in grub2, which sadly does not support
Xen, so it is useless in Qubes.
