autofs broken by yum update

[Mike Fleetwood]

Hi,

Sorry, this is a bit of a complaint, but others might experience the same
issue, and there is possibly an underlying reason / problem ...

Following a reboot the autofs service was failing to start because the
automount daemon was not able to read the master map auto.master.  File
/etc/auto.master had been renamed to /etc/auto.master.rpmsave.
   [root at rockover etc]# ls -lc auto.master.rpmsave
   -rw-r--r-- 1 root root 682 May  5 17:28 auto.master.rpmsave

Checking the yum log suggests that yum erased the autofs RPM, causing the
modified auto.master to be saved with the .rpmsave extension, and then
upgraded it.
   [root at rockover etc]# grep autofs /var/log/yum.log

   Mar 16 19:17:25 Updated: autofs.i386 1:5.0.1-0.rc3.26
   May 05 17:28:04 Erased: autofs
   May 05 17:28:44 Updated: autofs.i386 1:5.0.1-0.rc3.29

To fix the issue simply move the file back and start autofs.
   mv /etc/auto.master.rpmsave /etc/auto.master
   service autofs start

The interesting question is why did yum decide to erase autofs as part of
the upgrade procedure?

Thanks,
Mike
