Simon, have you tried building systemd with -Dstatic-libsystemd=true
-Dstatic-libudev=true ? Does this produce something useful?
Upstream doesn't seem to be too keen on supporting static builds, so if
we divert here downstream, I'd be interested if there is actual demand
from users of such a libsystemd.a or if this all mostly hyphothetical.
