Package: autofs
Version: 5.0.7-3
Severity: normal
Dear Maintainer,
* What led up to the situation?
We use autofs to mount home directories from a nfs4 server.
The clients get their IP address and so on from a DHCP server.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Boot the system.
* What was the outcome of this action?
autofs starts before the (rather slow) DHCP connection is initialised, so
the hostname lookup for the nfs4 server fails.
When the user tries to log on (after the DHCP connection has been initialised)
autofs still claims that it can't find the nfs4 server.
If autofs is restarted it works.
* What outcome did you expect instead?
Autofs should retry hostname lookups.
My autofs config is:
/etc/auto.master:
/home file:/etc/auto.home
/etc/auto.home:
* -fstype=nfs4,sec=krb5 olympic.calvaedi.com:/home/&
