Attached.
Additionally, when I run /lib/systemd/systemd-networkd manually, it works (as
root), so maybe it's a permissions problem:
# /lib/systemd/systemd-networkd
eth0: Gained IPv6LL
Enumeration completed
eth0: DHCPv4 address 10.0.0.73/25 via 10.0.0.5
lo: Configured
eth0: Configured
However, even non-root users can resolve the passwd entry just fine it seems:
# su -c "getent passwd systemd-network" -s /bin/sh nobody
systemd-network:x:101:103:systemd Network
Management,,,:/run/systemd/netif:/bin/false
Lastly, "No such process" seems to be a peculiar error, but it seems to be
generated by logic in the systemd code (which, btw., seems to errornously
assume that errno is 0 when a library call succeeds, in a lot of places -
fortunately only for error reporting it seems).
