I wanted to try boot system with init=/usr/lib/systemd/systemd . I uninstalled systemd-sysvcompat to be sure. With GRUB I didn't have problem, but with systemd-boot, I can't boot system.

If I put init=/usr/lib/systemd/systemd after /vmlinuz-linux

title Arch Linux linux /vmlinuz-linux init=/usr/lib/systemd/systemd initrd /amd-ucode.img initrd /booster-linux.img options root=UUID=my_uuid rw rootflags=relatime,compress-force=zstd:2,ssd,subvol=arch 

It shows me only reboot to UEFI (firmware) option.

If I try

title Arch Linux linux /vmlinuz-linux initrd /amd-ucode.img initrd /booster-linux.img options init=/usr/lib/systemd/systemd root=UUID=my_uuid rw rootflags=relatime,compress-force=zstd:2,ssd,subvol=arch

It show me

lstat /usr/bin/init: no such file or directory sh: can't access tty: job control turned off 

Any idea? Or with systemd-boot it's impossible?
