 Posted: Tue Oct 26, 2004 8:09 pm Post subject: autofs and automatic CDROM mounting. SOLVED with HOWTO |
 |
|
note: hotwo is at the BOTTOM.
Well, i don't know exactly if there is a forum for this, but anyway, here's the problem.
I think is ABSURD, STUPID and ANACHRONISTIC that, in 2004, people must have carpal tunnel syndrome for writing all the times that stupid commands "mount /cdrom", "umount /cdrom" and so on, and this for YEARS, on his own PC, with absolutely NO SECURITY PROBLEMS ....
i'm writing those ugly mount commands from about 20 YEARS, and now I'M TIRED. so, my goal is to have cdrom automagically mounted when i insert the cd, as i think it MUST BE in the THIRD MILLENNIUM.
so here's what i've done :
no problem here
| Code: | | enabled AUTOMOUNT v4 support in the kernel (2.4.25), make bzimage, lilo, and reboot. |
no problem here 
| Code: | configured autofs :
gemini autofs # pwd
/etc/autofs
gemini autofs # cat auto.master
/cdrom /etc/autofs/auto.cdrom
gemini autofs # cat auto.cdrom
cdrom -fstype=auto,ro :/dev/cdroms/cdrom0
|
this is what i red on other howto's ... i hope this is correct
| Code: | | rc-update add autofs default |
it seem all ok here
and, to try it:
| Code: | /etc/init.d/autofs start
gemini autofs # /etc/init.d/autofs start
* Starting automounter...
/cdrom [ ok ]
|
and I THINK THIS IS OK ... (looking into the VOID with WHITE EYES)
| Code: | some tests:
gemini autofs # mount
automount(pid3060) on /cdrom type autofs (rw,fd=5,pgrp=3060,minproto=2,maxproto=3)
gemini autofs # ps auxw
root 3060 0.0 0.1 1540 660 pts/1 S 19:54 0:00 /usr/sbin/automount --timeout 60 /cdrom file /etc/autofs/auto.cdrom
|
===============
and now, LET'S TRY THE HORRIBLE BEAST : i will take that ULTRA PORNO CD from my bookshelf and i will put into my cdrom reader.
ok.
now:
| Code: |
gemini autofs # ls /cdrom
gemini autofs # ls /cdrom
gemini autofs # ls /cdrom
gemini autofs # ls /cdrom
gemini cdrom # ls *
ls: *: No such file or directory
gemini cdrom # echo HELLOOO???? IS THERE ANY FILE IN THERE !??!?!?!?
-bash: !??: event not found
gemini cdrom #
|
==================================
i really don't know where i'm wrong. can someone
PLEASE HELP ME ???

I just tried Ivman (it's finally in portage) and it works quite well with the default settings. It just mounts the cd to /media/<watever> instead of /mnt/<whatever>. It's probably pretty simple to change, but I don't feel like doing it right now. It's just a quick solution in case nobody else can help you much with autofs.

Hi,
i solved the problem.
autofs have to be configured in this way:
| Code: | asbesto@gemini asbesto $ cat /etc/autofs/auto.master
# $Id: auto.master,v 1.1 2000/08/08 17:53:33 achim Exp $
# Sample auto.master file
# Format of this file:
# mountpoint map options
# For details of the format look at autofs(8).
/mnt /etc/autofs/auto.cdrom
#/home /etc/autofs/auto.home
|
and
| Code: | asbesto@gemini asbesto $ cat /etc/autofs/auto.cdrom
# $Id: auto.misc,v 1.2 2002/10/27 05:21:15 bcowan Exp $
# This is an automounter map and it has the following format
# key [ -mount-options-separated-by-comma ] location
# Details may be found in the autofs(5) manpage
#boot -fstype=ext2 :/dev/hda1
cdrom -fstype=auto,ro :/dev/cdroms/cdrom0
#floppy -fstype=auto :/dev/fd0
|
EXPLANATION:
in auto.master you specify "/mnt" as starting point for the
other mount points, and a file to configure them (in
our case, auto.cdrom)
in auto.cdrom you specify the mount point itself.
so if you want to mount the cdrom in /mnt/cdrom, you have
to specify /mnt in auto.master and auto.cdrom as file for
configuring the mount point; and cdrom in auto.cdrom
file.
I'M WONDERING WHY, WHY THE AUTHORS OF AUTOFS
CHOOSE THIS DAMN WAY of using SUCH A HORRIBLE
SYSTEM to configure a program!!! 
WASN'T MORE SIMPLE TO USE JUST ONE (1) FILE, with
something like
| Code: |
/mnt/cdrom /dev/cdrom options otheroptions
|
???!?!?!?!?
things like those are the DAMNATION of linux; so people choose
mac os-x and windows due to semplicity...
i hope we at freaknet medialab make a patch to autofs source
code to develop a more simple and automatic configuration scheme.

How to install autofs (automount) and configure it to have cdrom automagically mounted HOWTO
by asbesto at freaknet dot org
http://www.freaknet.org
1) install autofs:
2) let it start at boot:
| Code: | | rc-update add autofs default |
3) We here assume that /mnt will be the directory where all mounts resides, for example /mnt/cdrom, /mnt/floppy and so on (according to "man hier")
so edit /etc/autofs/auto.master like here:
| Code: |
gemini root # cat /etc/autofs/auto.master
# $Id: auto.master,v 1.1 2000/08/08 17:53:33 achim Exp $
# Sample auto.master file
# Format of this file:
# mountpoint map options
# For details of the format look at autofs(8).
/mnt /etc/autofs/auto.cdrom
#/home /etc/autofs/auto.home
|
We choosed auto.cdrom as configuration file for our cdrom. so, now, let's edit /etc/autofs/auto.cdrom like here:
| Code: | gemini root # cat /etc/autofs/auto.cdrom
# $Id: auto.misc,v 1.2 2002/10/27 05:21:15 bcowan Exp $
# This is an automounter map and it has the following format
# key [ -mount-options-separated-by-comma ] location
# Details may be found in the autofs(5) manpage
#boot -fstype=ext2 :/dev/hda1
cdrom -fstype=auto,ro :/dev/cdroms/cdrom0
#floppy -fstype=auto :/dev/fd0
|
ok. Now let's edit /etc/conf.d/autofs to set the timeout for automatic unmount of the cdrom:
| Code: | gemini root # cat /etc/conf.d/autofs
# Config file for /etc/init.d/autofs
#
# e.g. localoptions='rsize=8192,wsize=8192'
#
localoptions=''
#
# additional options for automount, ie. timeout
#
daemonoptions='--timeout 1'
|
As you can see, we set timeout = 1 second; so i can access the cdrom, do whatever i want, and after 1 second i can simply eject it
This is not slow due to caching.
Now, you have to COMPILE YOUR KERNEL enabling "AUTOMOUNT"
support V4 in the Filesystem section. Install the new kernel and
reboot.
After the reboot, you can simply access the /mnt/cdrom directory and you will have your cdrom contents automagically mounted without doing NOTHING.
NOTE:
i really hate this way of having 2 files for configuring such a simple thing like autofs.
it will be BETTER to have 1 SINGLE config file, something like
| Code: |
# Proposal for a new autofs single config file
#
# autofs mountpoint device mountpoint device options
/mnt /cdrom /dev/cdrom -fstype=auto,ro
|
Why 2 separate files ? why this stupid complexity ?
i hope we will develop a patch for autofs to use only 1 config
file instead of 2, here at freaknet medialab.
