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.
