Kernel 2.6.9, autofs v4 as a module, autofs-4.1.3-28 (FC3).  I added

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.

Bah, and it was just pointed out to me that this patch adds a bug.  I'll
repost the patch when the bug is fixed.  (see red hat bz #138994).
No ETA just yet.

New patch attached.  Let me know if you need an incremental.  This is as of
yet untested.
Incremental would probably be better if it's not to much trouble.
There will have to be quite a bit of testing when I'm finished patching. I 
expect it won't even compile first off.
