Oh, of course; the stop/pre-start message is precisely because the '|| {

Thanks for the hint!!
just mentioned that i set NEED_IDMAPD=y instead of =yes
Now the idmapd job can be started with service idmapd start.
However the logfile is empty:

Which version of Ubuntu is this? Your report doesn't mention. (Please
use
the 'ubuntu-bug' command for filing bugs, when possible.)
it's oneiric with latest updates
in /etc/default/nfs-common
# Do you want to start the idmapd daemon? It is only needed for NFSv4.
NEED_IDMAPD=y
is set.
FWIW, this is no longer needed as of precise.
No clue, how to debug the upstart job. But if i mount nfsd and
rpc_pipefs and then start rpc.idmapd -v -f it works.
If you happen to be using precise, you can boot with --log to get
logging
of
upstart job output. Otherwise, we can try to dissect this manually.
The
output of the start command suggests, however, that the pre-start script
has
decided idmapd isn't meant to be started; so further debugging requires
knowing which Ubuntu release you're running.
tried to debug it by my own. I added some 'exec echo' s into the
idmapd.conf:
pre-start script
exec echo hihi
do_modprobe() {
..
if ! mountpoint -q $PIPEFS_MOUNTPOINT
then
mount -t rpc_pipefs rpc_pipefs $PIPEFS_MOUNTPOINT
fi
exec echo 2
end script
exec echo 3
exec rpc.idmapd
...
However i can't see those prints in the syslog, but the idmapper
is now running after a reboot.
I'd like to understand what is happening here. Because the next
step is getting autofs with ldap working after startup that is
also not working 'out of the box' with ubuntu. :(
Thanks for your help

Ok. The oneiric upstart doesn't have the same job logging facilities that
we could use in precise to debug this.

pre-start script
exec echo hihi

Instead, please try adding just 'exec /var/log/idmapd.log 21' as the
first line of the pre-start script. This will give you a /var/log/idmapd.log
showing what's going wrong.
exec echo 3
exec rpc.idmapd
This is definitely broken. There should only be one 'exec' line. I don't
know which would take precedence when there are two of them.
However i can't see those prints in the syslog,
Yes, the output doesn't go to syslog.
but the idmapper is now running after a reboot.
Surprising. Can you reproduce the original failure now? Does 'status
idmapd' show the upstart job running?
