Kernel 2.6.9, autofs v4 as a module, autofs-4.1.3-28 (FC3). I added
"/net /etc/auto.net" to /etc/auto.master and it works fine, up to a
point. ps shows
/usr/sbin/automount --timeout=60 /net program /etc/auto.net
If the target server has a lot of mounted filesystems then automount
will only mount the first few entries on the list. Then it tries to
run mount with invalid input. It looks like there is a hard coded
limit on the string that automount expects from a program map. My
virtual CD server has lots of CD images mounted over loopback, each
with its own export entry, so the return string from auto.net is quite
long.
"/etc/auto.net virtcd" returns a long string, over 20K. The start of
this string is below, some of the names have been sanitized without
changing their length. irix-6.5.21-overlays-4 mounts correctly,
irix-6.5.22-applications-1 does not. Instead of issuing
/bin/mount -t nfs -s -o hard,intr,nodev,nosuid
virtcd:/virtcd/mnt/irix-6.5.22-applications-1
/net/virtcd/virtcd/mnt/irix-6.5.22-applications-1
it issues
/bin/mount -t nfs -s -o hard,intr,nodev,nosuid virtcd:/virtcd/mnt
/net/virtcd/virtcd/mnt/irix-6.5.22-applications-1
The NFS directory string has been truncated. Interesting that the
failure point is around the 4K mark on the input string.
