Is the "program" format correct ?

Is the "program" format correct ?

[Andreas Neuper]

Hello,

I am new to the list.  I wanted to use the program format to provide some good solution.
Unfortunately, it showed a strange behaviour.  It seems to me, nobody really ever used it!
Your example delivered with the distribuion works, although it should not IMHO.  
I would expect that the program format causes the same action as
e.g. a nis-map or a file. Maybe I am wrong with my expectations. 
Try this: 

~# cat /etc/auto.master
/auto   /etc/auto.auto

~# cat <<*** >/etc/auto.cat
#!/bin/sh
grep -v ^# /etc/auto.auto
exit 0
***
~# chmod a+x /etc/auto.cat
~# /etc/auto.cat

floppy  -fstype=auto                            :/dev/fd0
video   -fstype=nfs,rw,rsize=8192,wsize=8192    ok:/home/video

~# echo "/tmp/cat       /etc/auto.cat" >> /etc/auto.master
~# /etc/rc.d/autofs restart
~# ls /auto/video
.       ..      DVD
~# ls /tmp/cat/
.       ..
~# ls /tmp/cat/video
^C
~# tail -5 /var/log/messages
Aug  8 16:26:21 akemi automount[6212]: mount(nfs): host -fstype=auto: lookup failure
Aug  8 16:26:21 akemi automount[6212]: mount(nfs): host : lookup failure
Aug  8 16:26:21 akemi automount[6215]: mount(nfs): host floppy: lookup failure
Aug  8 16:26:21 akemi automount[6215]: mount(nfs): host -fstype=auto: lookup failure
Aug  8 16:26:21 akemi automount[6215]: mount(nfs): host : lookup failure

thanks for reading.  Is there a simple solution?
Andreas

I'm also using automounter program map.
It should behave like this:
~# /etc/auto.cat video
-fstype=nfs,rw,rsize=8192,wsize=8192    ok:/home/video

>~# echo "/tmp/cat       /etc/auto.cat" >> /etc/auto.master

~# echo "/tmp/cat       program:/etc/auto.cat" >> /etc/auto.master

Thank you Takashi,

this confirms my oppinion:  The format for program maps differs!
Usual and documented format is:
        key [-options] location

These maps swallow the key and accept only nfs location codes
where the hostname seems to be overwritten with the key. !?!

It seems strange to me. just try to use it for the floppy. I get 
errors on hostname resolution! (even when omitting the key) 

Is there a working release?

Not really.

It receives the key as a parameter.

Lookups always "lookup a key". The program map returns the map entry for 
the given key only. All the lookup modules work this way.

The confusion here is because you are seeing what the lookup module needs 
to complete its operation not what you expect a map to look like. It 
already knows what key it's looking for and doesn't want or need the key 
to be returned.

In what way are you using it with your floppy?

Program maps are something that are used by people like yourself. The 
auto.net is an example only.
