Okay:

/etc/auto.master:
/vol    /etc/auto_vol_linx_new

autofs5 version: 5.0.2-4, that is the same as in debian experimental
plus all patches from the kernel.org directory applied.

auto_vol_linx_new contains:

eclipse-3.1 \
   /bin          -rw,nosuid,grpid          fileserver:/volumes/vol1/eclipse-3.1/bin.linx86
eclipse \
   /bin          -rw,nosuid,grpid          :/vol/eclipse-3.1/bin

Which should bind-mount /vol/eclipse/bin from /vol/eclipse-3.1/bin, and
nfs-mount /vol/eclipse-3.1/bin from the fileserver.

lkolbe@lahn cgrep /etc/nsswitch.conf 
passwd:         compat
group:          compat
shadow:         compat
hosts:          files dns mdns
networks:       files
protocols:      db files
services:       db files
ethers:         db files
rpc:            db files
automount:      files nis
netgroup:       nis

lkolbe@lahn cgrep /etc/default/autofs
MASTER_MAP_NAME="/etc/auto.master"
TIMEOUT=300
BROWSE_MODE="no"
LOGGING="debug"

Trying to reproduce it:

lkolbe@lahn ls -la /vol/eclipse/bin/
ls: /vol/eclipse/bin/: No such file or directory

lkolbe@lahn ls -la /vol/eclipse-3.1/bin/
total 0
drwxrwsr-x 2 root eclipse 96 2007-09-12 14:34 .
dr-xr-xr-x 7 root root     0 2007-10-02 12:16 ..
-rw-r--r-- 1 root eclipse  0 2007-09-12 14:34 foo

lkolbe@lahn ls -la /vol/eclipse/bin/
ls: /vol/eclipse/bin/: No such file or directory

And a few seconds later:

lkolbe@lahn ls -la /vol/eclipse/bin/
total 0
drwxrwsr-x 2 root eclipse 96 2007-09-12 14:34 .
dr-xr-xr-x 8 root root     0 2007-10-02 12:16 ..
-rw-r--r-- 1 root eclipse  0 2007-09-12 14:34 foo

daemon.log comes in the next mail.
