Re: auto.net gets a key with a path under SLES9.

Greetings.


   Well, I successfully reproduced the problem of a path sent to 
auto.net (see below for full description).  Attached, the debug output 
on syslogd.  From what I understand of the syslogd logs, the problem 
occurs before sun_mount() is called.

   What I did was:

   cd /net/asterix  # Everything is ok.  $key=asterix
   cd asteris-07    # Bug:  $key=asterix/asterix-07

   What was passed to auto.net was asterix/asterix-07 at the second 'cd'.

   And there is some confusion.  The directory structure should be:

# pwd
/net/asterix
# ls -l
drwxr-xr-x  4 root root 8192 Jun  1 16:23 asterix-00
drwxr-xr-x  5 root root 8192 Sep 20 09:06 asterix-01
drwxr-xr-x  4 root root 8192 Jun 29  2004 asterix-02
drwxr-xr-x  5 root root 8192 Feb 13  2004 asterix-03
drwxr-xr-x  4 root root 8192 Oct 17 07:18 asterix-04
drwxr-xr-x  4 root root   96 Sep 22 13:29 asterix-05
drwxr-xr-x  4 root root   96 Nov  3  2004 asterix-06
drwxr-xr-x  4 root root   96 Nov  3  2004 asterix-07

However, I notice the following:

# pwd
/net/asterix/asterix-07
# ls -l
drwxr-xr-x  4 root root 8192 Jun  1 16:23 asterix-00
drwxr-xr-x  5 root root 8192 Sep 20 09:06 asterix-01
drwxr-xr-x  4 root root 8192 Jun 29  2004 asterix-02
drwxr-xr-x  5 root root 8192 Feb 13  2004 asterix-03
drwxr-xr-x  4 root root 8192 Oct 17 07:18 asterix-04
drwxr-xr-x  4 root root   96 Sep 22 13:29 asterix-05
drwxr-xr-x  4 root root   96 Nov  3  2004 asterix-06

   This is not right.  The content of /net/asterix/asterix-07 is not 
supposed to be the same as /net/asterix.  Something recursive is going on.

I went so far as:

# cd asterix-07
# pwd
/net/asterix/asterix-07/asterix-07
# cd asterix-07
# pwd
/net/asterix/asterix-07/asterix-07/asterix-07
# cd asterix-07
# pwd
/net/asterix/asterix-07/asterix-07/asterix-07/asterix-07

   You see?  Automount fall in a recursive condition.

   Autofs 4.1.4 was used.  What was running was:

/usr/sbin/automount --debug --ghost --timeout 60 /net program /etc/auto.net

   Let me know if you find something strange in the output.  What I do 
not understand, is the asterix-06 mountpoint.
