Changing /etc/auto.master to say
/net    -hosts
hides this bug.  I'm keeping it open pending an actual diagnosis and fix.

Wow, what on Earth is going on there?  Ian, is this after incorporating your patch that changes from select to poll?  I wonder if that's mucked up program maps.

FWIW, here's the output from /etc/auto.net:

$ /etc/auto.net fenlason-desk
-fstype=nfs,hard,intr,nodev,nosuid \
        /local fenlason-desk:/local \
        /mnt/local fenlason-desk:/mnt/local

It looks like the quoted flag is never cleared.

clear the quoted flag after each character is processed

This regression was introduced by autofs-5.0.4-fix-select-fd-limit.patch.  The fix is to clear the quoted flag after processing each character.  Or, at least I think that's the fix.  ;)  Jay has agreed to test this patch for us.
Comment 12 Jay Fenlason 2009-01-21 21:18:30 UTC 
Yes, the patch works.
Comment 13 Jeff Moyer 2009-01-21 21:58:11 UTC 
A fix for this has been committed and will appear in autofs versions 5.0.4-6 and later.

Good catch Jeff.
Committed upstream.
