Program maps - examples?

Program maps - examples?

Hello,

I'm new to this list and have the following problem:

I wan't to automount home directories from a file server on a linux
machine. The problem is that the tree on the server is different from
the what it looks like when mounted:

Local: 	/level1/level2/home/username
Server: /prefix/homestore_[:a-z:]/username

This means when I want to mount my own home I have to mount
server:/prefix/homestore_d/dheinric to /level1/level2/home/dheinric. I
guess there's no other way than using a program map, but there's not
much documentation/examples about this in the package. Can someone sched
some light on this, please.

I've also looked onto our Solaris machines. They seem to cascade the
maps, which I guess is not possible on linux, right?

Thanx...

	Dirk

Tried this, but did not quite succeed. The problem is that this would 
require entries for every single user. But the following auto.home then 
worked for me:

#!/bin/bash
FIRST_LETTER=`echo $1|cut -c 1`
echo server:/prefix/homestore_${FIRST_LETTER}/$1

This returns the correct path.

In auto_master they have a line "/level1 auto_level1", then in 
auto_level1, there is "level2 -fstype=autofs auto_level2", this is what 
I mean with cascading. Meanwhile, I found another Linux box here which 
does the same, but the syntax is different: "level2 -fstype=autofs 
file:/full/path/to/map"

Bye...
