NIS-based autofs maps don't load on startup

Bug Description

Binary package hint: autofs5

I have all of my automount maps in NIS. Automount starts, but fails to load the maps on startup.

I would guess that the problem is that NIS starts after autofs:

rd-xd-faulk% ls /etc/rc3.d/S*{nis,autofs}*
/etc/rc3.d/S19autofs /etc/rc3.d/S99nis

(Same sequence numbers for runlevels 2, 4, and 5, as well.)

I had a similar problem under 9.10 that I never bothered to track down.

Looks like a dupe from bug 533029 ...
Any chance you could upgrade to autofs5 5.0.4-3.1ubuntu5 and check that it also fixes it for you ?

That did not fix the problem.

This line from syslog looks relevant:

automount[1378]: lookup_init:136: lookup(yp): map auto.master: Local domain name not set

It looks like nis hasn't been converted to upstart, and autofs therefore can't depend on any event it might emit.

I forgot to mention it, but if I stop/start autofs or reload autofs, the automounts start working.

Thierry Carrez (ttx) wrote :

The issue is that autofs is now an upstart script but NIS wasn't converted to upstart yet. So nothing ensures that NIS is started before AutoFS.

A workaround would be to reload AutoFS in /etc/rc.local, since S99rc.local should always run after S99nis.

I'm also hitting this problem. Obviously the correct solution is to move nis to use upstart and then make autofs depend on nis being up. In the interim, I've modified autofs.conf to wait for the rc process to finish:

  start on (filesystem
        and net-device-up IFACE!=lo
        and stopped rc RUNLEVEL=[2345])
  stop on runlevel[!2345]

Reloading autofs in /etc/rc.local doesn't work for me as my /usr/local is also automounted and seems to be busy at that time which makes autofs restart freeze.

@Lars Kellogg-Stedman: thanks, that does seem to work for me although I wonder what the side effects might be. If I understand this correctly it will make autofs start after everything else starts, right?


@Dern: That's correct, anything started out of /etc/init.d will start up before autofs with this configuration. My solution is really just a hack to work around the fundamental problem.

This should be fixed when bug 569757 is fixed (migration of NIS to upstart).

This bug also breaks gdm on NIS accounts with automounted NFS home directories !

This is a patch a applied to /etc/init/autofs.conf to make the autofs upstart job wait for NIS.

The loop was inspired by the same loop in /etc/init.d/nis.
