pacstrap, the arch-bootstrap tarball and the Arch installation media already
have systemd pulled, so far, I didn't notice a change.

Since filesystem use systemd-sysusers to initialize our users/groups, it should
deps on systemd. It was suggested by Evangelos in FS#55492, but this create a
circular deps, because filesystem <- systemd <- glibc <-  filesystem.
Maybe it's a better solution to make gblic drop filesystem dep and add a
systemd dep to filesystem.

However, put systemd  in the base-devel make also sense like having glibc or

I don't think lp is a systemd bug, but a mistake from my side. I forgot to add
it or to ask for moving it like i did for mlocate (FS#53539) or rfkill
(FS#53525). It looks like the lp group is tied to cups and not multiple
packages; do you think it should be moved to cups package?

About the systemd bug, Lennart just pushed a fix which should land in v235. In
the mean time, I think to push a new version with root and nobody defined in
files to not have sshd segfault on new installations.

Groups are a shortcut to pull a collection of packages. They are not designed
to guarantee a set of packages remain installed. Your removal of systemd-
sysvcompat is one example. If we want to have a set of package installed on all
our Arch, we should use a base package which pull these packages.
