Mounts disappear when using bind mount to automounter point

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.5) Gecko/20011012 Description of problem: I haven't been able to test this against RH7.2, but on RH7.1, the problem is as follows: We have an automounter (autofs) set up to automount into the /data automount point, e.g. /data/caldb automount(pid772) on /data type autofs (rw,fd=5,pgrp=772,minproto=2,maxproto=3) xalph3.ast.cam.ac.uk:/soft3/caldb on /data/caldb type nfs (rw,addr=131.111.68.53) If I then use the --bind option on mount to bind this directory to another one: > mount --bind /data/caldb /caldb /data/caldb on /caldb type none (rw,bind) It works fine, but when the automounter point expires, the bind mount expires. I'd say this is a bug. We could symlink to the automounter point, but what is the preferred solution? Version-Release number of selected component (if applicable): mount-2.11b-3 kernel-2.4.3-12 autofs-3.1.7-14 How reproducible: Always Steps to Reproduce: 1. Make a bind mount to an automounter point 2. Wait for automounter to unmount point 3. Bind mount disappears. Additional info:
IMO the automount point shouldn't expire while there's a bind mount... Reassinging to am-utils.
It works like u expected in current fedora core 4. autofs-4.1.4-8 util-linux-2.12p-9.7 kernel-2.6.12-1.1398_FC4 btw. I don't know why this bug was reassigned to am-utils.
