title: Partition mounted on boot, but not listed not in fstab
body: <p>I thought I was a fairly advanced Linux administrator working on a Centos (Fedora) machine.  I have modified fstab to not mount a particular partition at boot, yet it keeps mounting.  It is no longer in fstab, but I can see it mounted in mtab (last line) on reboot.  It is immediately mounted, as soon as I login.  Any idea at what point during a reboot this partition could be mounting?  I didn't see anything in cron, but not certain.  any ideas on where to look for clues would be great.  Thanks in advance.</p>

  <p>EDIT: I did turn off autofs (according to solution provided) in chkconfig and reboot, but the directory was still mounted. Aside from fstab what are the possible ways to mount a drive/folder during or immediately after boot?</p>
