Hello all,
I think automounting is more practical than doing "mount /cdrom" all the time. I know Linux has "autofs" service which can do that. I enabled it using "ksysv". However, automounting of cds and dvds are not working. I have just tried, I was able to mount a CD-R and a DVD-RW disk in my Inspiron 8600's combo DVD+RW/CD+RW drive.
Moreover, I cannot play nor mount a music cd.
Trying to explore how automounting is configured in my Debian 2.4.23-xfs-acpi, I found out that /etc/auto.master is like this:
------------------------
# Sample auto.master file
# Format of this file:
# mountpoint map options
# For details of the format look at autofs(5).
# /var/autofs/misc /etc/auto.misc
# /var/autofs/net /etc/auto.net
#
# KNOPPIX automounts for floppy and cdrom(s), see knoppix-autoconfig
# /mnt/auto /etc/auto.mnt --timeout=2
/mnt/auto /etc/automount.sh --timeout=2
----------------------------------------
The file /etc/automount.sh mentioned in the line above is like this:
----------------------------------------
#!/bin/bash
# Generate an automounter entry automatically
# for automount /mnt/auto program this_script
# (C) Klaus Knopper 2002
# WARNING: This script is used for removable media in KNOPPIX,
# therefore the mount is always read-write (except for cdroms
# and ntfs).

------------------
I also do have /etc/auto.mnt, like this:

# Knoppix automounter file for Directory /mnt/auto
# umask=000 only works for msdos/vfat floppies, but otherwise the floppy is read-only.
floppy -fstype=auto,user,exec,umask=000 :/dev/fd0
cdrom -fstype=auto,user,exec,ro :/dev/cdrom
# The following entries (if any) are auto-generated by knoppix-autoconfig
-------------------
I would like your comments as to how to proceed to solve these two problems.
Thanks a lot for your time and effort.
Best,
