I can confirm this, by installing network-manager, nfs-kernel-server,
and setserial into a clean VM. setserial's init.d script is very
demanding as it both wants to start in run level "S" (sysinit.target in
systemd's mapping) *and* requires $remote_fs. But we can't start remote
file systems that early if we need NetworkManager for them, this only
works with very simple networking like ifupdown.
I suppose /etc/init.d/setserial wants $remote_fs as it reads stuff from
/var/lib/setserial/ which might potentially be on NFS. Having setserial
on an NFS /var with NetworkManager is certainly a very special case, and
I suppose we could just ignore it. But I think we can relax the early
startup instead.
As far as I can see, the most appropriate course here is to provide a
systemd unit for setserial with more fine-grained ordering, or just a
drop-in to relax the overly harsh "Default-Start: S" (as it really just
Before=system-getty.slice). I don't want to completely replace the
init.d script as it has lots of code (which really doesn't belong there,
but I leave that to the Debian maintainer, and this is too intrusive for
an SRU).
** Package changed: nfs-utils (Ubuntu Wily) => setserial (Ubuntu Wily)
** Changed in: setserial (Ubuntu Wily)
Status: Triaged => In Progress
** Changed in: setserial (Ubuntu Wily)
Assignee: (unassigned) => Martin Pitt (pitti)
** Summary changed:
- vivid NFSd does not start due to systemd ordering cycle
+ NFSd does not start due to systemd ordering cycle with setserial
** Description changed:
NFSd does not start due to systemd ordering cycle.
Manually starting with "systemctl start nfs-kernel-server" after boot
works fine.

- Description: Ubuntu 15.04
- Release: 15.04
+ SRU test case
+ =============
+ - Install network-manager, nfs-kernel-server, and setserial into a clean
vivid VM.
+ - Reboot, and you'll find the above ordering cycle (check "sudo journalctl
-p warning"). "systemctl status nfs-server.service" will be not running (it
could also be that the cycle gets broken on a different point, but that's the
most likely one).
+ - With the fixed setserial package (upgrade, then reboot) there should be no
cycle and all services start up normally.
