Description Jacob Beacham 2005-04-19 17:04:38 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050414 Firefox/1.0.3

Description of problem:
Ghosting of automounts is currently all-or-nothing, as specified by
the presence or absense of "--ghost" in the variable DAEMONOPTIONS in
/etc/sysconfig/autofs.  It would be very nice if you could specify which
mounts you'd like to be ghosted, instead of all or none.

Version-Release number of selected component (if applicable):
autofs-4.1.3-47

How reproducible:
Always

Steps to Reproduce:
N/A

Additional info:

A particular fix we used was a change to /etc/init.d/autofs, which allowed
us to specify which automount points we wanted ghosted, instead of having
an "all or nothing" situation.  It would be nice to see this implemented
natively as well.  It was very simple to write, only a few lines:

ghostdirs="$(echo "$GHOSTDIRS" | sed 's/ /\|/g')"
if echo "$dir" | grep -qE -- "^($ghostdirs)\$" ;
then
    startupoptions="$startupoptions --ghost"
fi

This allows us to specify a space-delimeted list of target mount points
that we want ghosted through the variable GHOSTDIRS in /etc/sysconfig/autofs.
This isn't a permanent fix, but we were able to only ghost project and scratch
space, while keeping system mounts un-ghosted.
Comment 1 Jeffrey Moyer 2005-04-19 19:53:08 EDT
I'm not sure how this is any easier than modifying /etc/auto.master.  One thing
I guess it gains you is the ability to specify ghosting of maps when the
auto.master is not controlled by you (i.e. when it is in NIS or ldap).  Is this
your situation?

At any rate, this is a reasonable request.  If it makes your life easier, then
I'll certainly try to get this into the next round of updates.
Comment 2 Jacob Beacham 2005-04-20 17:14:23 EDT
Actually, yes, we use NIS for everything, and would like to have these settings
be local.(In reply to comment #1)
Comment 8 Jeffrey Moyer 2005-07-15 11:56:06 EDT
A fix for this was just committed to version 4.1.3-142 of autofs.
