probably it's because of missing unix, autofs4 or ipv6 modules (or
built-in support).

while unix and autofs4 are required, ipv6 should be optional and I'll
send a patch later today for it. Anyway, if its is ipv6 don't worry as
it is just informative.

these are due ipv6, my patch will fix them as well.

you need udev and dbus with --with-systemdsystemunitdir=/lib/systemd/system

these should make it work. If you don't need sysv init compatibility,
then check out the patch I've send... at least it will remove some
stat/open and avoid some checks you don't need.
