Description Steven Roberts 2004-10-17 01:59:17 UTC
Description of problem:
With update3, autofs was upgraded to version 4.1.3-12 from version
3.1.7-41.  with that update support for file based maps when the map
name in auto.master is a plain name (with an assumed prefix of /etc/)
is broken.

in particular in /etc/rc.d/init.d/autofs, getmounts function, these
lines were dropped:
  elif [ -f "/etc/$map" ]; then
      map=`echo /etc/$map | sed 's^//^/^g'`

I was not expected breakages in compatibility like this within a given
major RHEL release.

with these lines missing, the map is assumed to be YP (falls through
to the bottom of the loop).  The automount entry in nsswitch.conf is:
automount:  files

Also, I am not sure if I can change the map name in auto.master as
some RH versions I think didn't support an absolute pathname as a map
name.  And the auto.master file is synchronized with a global network

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

How reproducible:

Steps to Reproduce:
1. have a map in auto.master with a simple name (for example 'auto.home').
2. start up autofs
Actual results:
no map is loaded for auto.home and thus home directories don't get mounted

Expected results:
/etc/auto.home would get loaded and /home would get mounted by autofs

Comment 1 Steven Roberts 2004-10-19 19:57:17 UTC
Since I had to get the new boxes up, I went through the scripts for
rh6.2,rh7.3,rhel as2.1 (the versions we principally run at the moment
-- we also have rhel es2.1 and as2.1 for ia64 but I am figuring they
have the same scripts as rhel as2.1).  They do support an absolute
path for the map name.  tested and it works.

So I converetd the global config files to this.  so I have a work
around for me.

And adding those lines may cuase issues to people who use YP/NIS.  The
change though probably would be good to note in the RELNOTES when it
discusses the autofs version upgrade.
