What happened?

Hi,

On CachyOS we wanted to switch the bootloader to systemd-boot for the ISO due following archlinux upstream (https://gitlab.archlinux.org/archlinux/archiso/-/merge_requests/374).

Ventoy is not able to boot from the ISO and does not find the disk e.G:
Waiting 30 seconds for device /dev/disk/by-label/....

after that it fails.

We have tried multiple ways to detect the Image when systemd-boot is used:

• Label
• archisosearchuuid (https://gitlab.archlinux.org/archlinux/archiso/-/merge_requests/372)
• archisodevice

Using GRUB 2 mode does fix the issues, but this is actually not a solution.

Second Issue, when Grub as ISO Bootloader is used

Additionally archlinux introduced recently including the ucode into the initramfs. When this mkinitcpio hook is used, it results also into a not bootable ISO with the grub bootloader.

Edit:
archiso 77 was used to build the ISO

This CI release should have fixed this issue.

Hi @ventoy, thanks this did resolve microcode issues.

Actually we are facing another, that mkinitcpio-archiso can not find the UUID, when using systemd-boot as bootloader on the ISO.
Grub as bootloader works. Also booting the ISO from etcher, rufus or QEMU does also work without problems. Only Ventoy provides problems.

This issue is not present on the archlinux ISO, im not sure, if there are any expections on archlinux set, so that is not happening on archlinux.

Weve set the same parameter for the bootflags as archlinux.
You can find the issue of the attached image:

I have also uploaded the failing ISO here , weve also increased the root wait to 10s, not that it would be to slow to find it.
