Make sure that you have a "/usr/lib/autofs/mount_autofs.so" around to
handle the "-fstype=autofs" submounts. My SuSE 6.1 installation left
that out (along with a couple of other types). I believe I did get
a log message, though. Also make sure your submount files are not
marked executable, unless you are intentionally using "program" maps
(in which case, read on).
I had a terrible time getting submounts working, partly because of the
above, but mostly because I tried to use program maps, and took quite
a while to realize the docs were wrong.
A map can be marked as executable. The init script that
parses the auto.master map will pass this as a program map
to the automounter. A program map will be called as a
script with the key as an argument. The script needs to
return one line of a map or no output at all if the key
^^^^^^^^^^^^^^^^^
cannot be matched.
Actually, in current versions the key field must be left out, or
symlink chaos ensues. Here is what I am using to get as much mileage
as possible from an in-house Solaris direct-style NIS map:
==== auto.master ==========================================================
#
# Autofs automount master map
#
# To pick up changes, use:
# /etc/rc.d/init.d/autofs stop && /etc/rc.d/init.d/autofs start
#
# Format of this file:
# mountpoint map options
# For details of the format look at autofs(8).
#
/misc /etc/auto.misc
/disks /etc/auto.org_exports
===========================================================================
==== auto.org_exports =====================================================
#!/bin/sh
#
# make direct map from NIS usable by current Linux autofs.
echo "$0: $1" >> /tmp/autoout
ypc=/usr/bin/ypcat
[ -x "$ypc" ] || exit 0
if $ypc -k auto.exports | grep -e '^/disks/'"$1" 2>&1 >/dev/null; then
echo '-fstype=autofs' "program:/etc/auto.org_exports_sub"
fi
===========================================================================
==== auto.org_exports_sub =================================================
#!/bin/sh
#
#
echo "$0: $1" >> /tmp/autoout
ypm=/usr/bin/ypmatch
[ -x "$ypm" ] || exit 0
# relying on `pwd` seems a little bold...
# If we use "-k" we really go to jail. UTSM trumps RTFM here.
exec $ypm `pwd`/$1 auto.exports 2>/dev/null
===========================================================================
This allows me to get to a bunch of in-house filesystems without
wasting too much time when I run into now-nonexistent /disks/*/* mounts
via symlinks. I don't get the nice browsing of available mounts that
Solaris gives me with "cd /disks && ls", though. Sigh.
