Makes sense.

I'd probably leave this in the main RPM, after all it doesn't take
possession of any interfaces by default, but makes sure
libsystemd-network returns useful stuff.

But if you do split it out, I'd call the package without the "d" suffix.

What's the effective size of this RPM on x86-64?

I'd call this "systemd-nspawn.rpm", really... The name of the daemon
is irrelevant.

I'd really not bother with this stuff. This should be in the base, and
it is tiny. Plese leave this in the main package.

sysusers is definitely something we should make a Fedora default, that
is used distro wide, as it makes user registration portable, and is
also what Atomic wants.

THe factory code is in systemctl and PID 1, it makes no sense to split
out, there's nothing really you could split out.

This makes sense to split out.

>From my perspective the only things that make sense to split out is
nspawn/machinectl/machined/importd/pull into "systemd-nspawn.rpm", the
hwdb into "systemd-hwdb.rpm" and "systemd-journal-remote.rpm" for the
journal remoting things.
