libinput has systemd-devel (or equivalent) listed as required OS dependency, which is going to be quite painful on many systems...

Are you sure we need this as extra dependency here?

AI says it will use a fallback for simple inputs like mouse and keyboard, so perhaps ok without it.

I'll comment it out, but we'll want to add it back for EESSI
