XBOOTLDR on EXT4: systemd-boot fails (?) loading ext4_x64.efi

I'm happily wasting my time big_smile discovering the systemd-boot world, just for fun / curiosity.
So, I'd say that's more a "gossip" post, rather than an "asking-for-support" one.
Let me know if this would still fit into System Administration, anyway.


CHANGES WITH 250:

[...]

*	sd-boot gained support for automatically loading all EFI drivers
	placed in the /EFI/systemd/drivers/ subdirectory of the EFI System
	Partition (ESP). These drivers are loaded before the menu entries are
	loaded. This is useful e.g. to load additional file system drivers
	for the XBOOTLDR partition.

https://github.com/systemd/systemd/blob … 1-L3181C38

# bootctl --esp-path /efi --boot-path /boot --efi-boot-option-description=gomma install

ESP    /dev/nvme0n1p1 [FAT32] on /efi
XBOOTLDR    /dev/nvme0n1p2 [EXT4] on /boot
ROOT    /dev/nvme0n1p2 [EXT4] on /

Installed both efifs and refind.

Tested booting with efifs-x64/ext2_x64.efi:

# cp /usr/lib/efifs-x64/ext2_x64.efi /efi/EFI/systemd/drivers/

and refind/drivers_x64/ext4_x64.efi:

# rm /efi/EFI/systemd/drivers/ext2_x64.efi
# cp /usr/share/refind/drivers_x64/ext4_x64.efi /efi/EFI/systemd/drivers/


Firmware loads systemd-boot just fine, but then systemd-boot itself fails on recognizing XBOOTLDR.
I suspect uEFI HP's firmware implementation is NOT capable of loading third-party *.efi drivers, but...
    shouldn't systemd-boot be in charge of loading $ESP/EFI/systemd/drivers/*.efi on its own, regardless Firmware capabilites?
    What's your thoughts about?

My next try is goin' on booting  UEFI Shell (/efi/shellx64.efi):

load ext4_x64.efi
map -r
systemd-bootx64.efi



I'm booting with GRUB atm, everything's fine.

What does this mean, exactly? Give errors, not your conclusion.

OK, let's add some more reports here...

Mmm... I was wrong, firmware can load ext4-x64.efi driver (/usr/share/refind/drivers_x64/ext4_x64.efi one) from UEFI Shell indeed.

Re: XBOOTLDR on EXT4: systemd-boot fails (?) loading ext4_x64.efi

Does your XBOOTLDR partition have the correct partition type UUID?

Edit: typos.
