[autofs] mount fails because entry in multi-mount doesn't work

[Tom Georgoulias]

Yesterday I ran into an issue where a mount point wasn't working and 
tracked it down to one of the submounts.  From what I can tell, if one 
of the submounts in a multi-mount doesn't work, the entire mount point 
won't work.  If that is the case, can this behavior be changed?

System:
Sun V20Z running RHEL3 WS AMD64, 2.4.21-15ELsmp (with 
kernel-smp-unsupported-2.4.21-15.EL RPM to get autofs4 module) and 
autofs-4.1.2-6 from Jeff Moyer.

Noticed how mount failed for /proj/tec/layout/maskprep1, then the whole 
/proj/tec/layout mount fails.  The mount point it was failing on is 
intentionally unshared at the moment, so I'm not surprise it couldn't 
make it. Took the entry out of the automount map

layout \
/copperhead eclipse0:/export/layout/copperhead \
/maskprep1 macduff:/fsys/fs04/maskprep1 \
<snip>
refreshed the automount daemon's cache.  Mount works now.
