bootctl: unrecognized option '--root'

[vt-alt]

We use mkosi to boot-test LKRG on GA on Ubuntu bionic, focal, jammy, kinetic. Since v15 mkosi is unable to build images on any of these Ubuntus with:

It seems even on latest Ubuntu kinetic bootctl does not support --root:

root@ubuntu-kinetic:~# bootctl --root
bootctl: unrecognized option '--root'

How it should be used now when WithUnifiedKernelImages is dropped too?

[behrmann]

The WithUnifiedKernelImages is only dropped main branch, where you will need a bleeding edge repart, see #1290.

[vt-alt]

I see only main branch here, perhaps you suggesting to stay on v14 tag? That's what I thought too.

[DaanDeMeyer]

Yes, main branch will only work if you build systemd from source and even then has breaking changes. Please stick to a release tag if you don't want to build systemd from source.

Thanks for suggestions.
