| I'm an idiot. I was using development-sources, not gentoo-dev-sources. Maybe that's my problem. Perhaps the gentoo patches for supermount will work better. |

You can create these icons yourself, like this (i'm using a localized version of KDE, so i translated the menu entries back to english. They might differ on your version).
Just right-click on your desktop to bring the desktop menu up. From this menu, choose `Create New' and select CD/DVD-romplayer. It will popup a new dialog window asking you to give the shortcut a name and select a station (third page). Hit oké, and you'll be all set. KDE will keep track of mounting and unmounting, although for me personally i still prefer the supermount way.

supermount shows up as red in vi, and whenever I try to mount it, I get: "mount: wrong fs type, bad option, bad superblock on none,
or too many mounted file systems."

You aren't passing the options correctly. You need to read /usr/src/linux/Documentation/filesystems/supermount.txt
You don't want these to be user, since they should all be automatically mounted. Any options to be passed to "mount" need to be after an option "--", so you should have something like:
| Code: | # Supermount stuff
none /mnt/cdrom supermount dev=/dev/cdroms/cdrom0,--,gid=19 0 0
none /mnt/cdrw supermount dev=/dev/cdroms/cdrom1,--,gid=19 0 0
none /mnt/floppy supermount dev=/dev/fd0,--,sync,rw,gid=11 0 0 |
sync is always a good idea to include on a floppy.

Just wanted to note that supermount did some weird things (like claiming the cdrom was mounted but showing nothing with ls) with fs=auto changing it to fs=iso9660 solved this problem though.
I was using supermount-2.0.3b-2.6.1 and an unpatched 2.6.1 kernel
Nice guide, supermount rocks  |

Hi,
I compiled supermount in the kernel, and adjusted my /etc/fstab just like you said, but nothing happens when I go for example inside the /mnt/cdrom directory. If I umount and mount it again, the same problem occurs. The directory is empty and my device is not reading.
Do you know what's wrong here?
I' m using gentoo-dev-sources 2.6.1-r1
Kind regards,

Can you post your /etc/fstab?

This looks fine, other than you should probably replace the "user" option for the floppy with "sync".
After you edited /etc/fstab did you mount the partitions? (You have to mount it to tell the kernel to use supermount to watch that partition.) In the future this will be taken care of for you automatically when you reboot.
So the procedure to initially start it working is:
include /mnt/cdrom supermount entery in /etc/fstab
mount /mnt/cdrom (as root)
Then the cdrom will be automatically mounted and unmounted as accessed/ejected.

The entry is correct in /etc/fstab as you said.
I tried to mount it as root but then I get this:
providence / # mount /mnt/cdrom/
mount: permission denied
Why is this?
Kind regards,

I too had to use "fs=iso9660" in my /etc/fstab, instead of "fs=auto". But works after that. If its not working for you, i know this sucks...but you should try rebooting. I only say that because you are modifying kernel modules, or builtin parts. Supermount will then get the right information from fstab when its loaded on bootup. Thanks.

I changed the filesystems of the floppy and cdrom devices to vfat and iso9660 respectively, and it works like a charm now!
Thanks for your advice!

|
|
First of all, many thanks to wolvenwraith for posting this how-to, and to all of the other folks who have contributed to the thread.
Following the how-to, I found that my just compiled 2.4.22 kernel has supermount support patched in and activated already, so I just edited the fstab to add the following -
| Code: |
# Removables *************************************************************
#/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro,user 0 0
none /mnt/cdrom supermount fs=auto,dev=/dev/cdroms/cdrom0,ro,--,iocharset=iso8859-1,codepage=850,umask=0 0 0
#/dev/fd0 /mnt/floppy auto noauto,user,noatime 0 0
none /mnt/floppy supermount fs=auto,dev=/dev/fd0,--,user,rw 0 0
|
What I find is that supermount works perfectly from a shell, but I cannot access it from any of KDE's GUI file managers. KDE dosen't seem to know the drives are mounted. From within Konqueror, for instance, if I select the /mnt directory, Konqueror freezes forever, and once froze KDE compleatly, such that I could not cntrl-alt-bkspc or cntrl-alt-f2 to another vterm.
The machine is a ThinkPad T20 with a superbay, or whatever they call it, which accepts either the DVD-ROM reader or a 3.5" diskette drive. The behaviour is the same for both drives.
I have tried changing the file system on the cdrom to ISO9660, and also (as you can see) tried adding options to the cdrom line which came from the previous LM9.1 setup on this machine, on which supermount worked like a champ. None of the changes made any difference.
So, is there anything suspicious looking about my fstab, or does anyone know how to let KDE know about the supermount?
Thanks again for this thread, and thanks in advance for any thoughts on my situation.

Well the only thing I noticed was the placement of the ro option, should be like this. I don't think this will make a difference, but my as well give it a shot. Anyways I'm in a hurry, so see ya
| Code: | | none /mnt/cdrom supermount fs=auto,dev=/dev/cdroms/cdrom0,--,ro,iocharset=iso8859-1,codepage=850,umask=0 0 0 |

Thanks for the reply, wolvenraith.
With the ro in the proper place, it now works sometimes. Sort of. Very slowly. That is, if I click on the /mnt dir, it will do nothing apparent for 2 to 5 minutes, then show me the subdirectories (cdrom and floppy). It I click on a subidrectory, it freezes forever.
Wierd.
BTW, this is a locally compiled 3.1.5 KDE, if that matters (compile options?).

I have a interesting problem. Everything works fine as far as accessing and changing the CD or floppy, but the light stays on on the floppy drive. Why it do that?
If I eject the floppy, it goes off. It does not sound like it is turning the floppy, just the light is on.
Kernel version: 2.6.1-rc1 Somebodies got to test the thing.
Anybody else have this little problem? It works, just curious.
Great how to. First time I ever got a patch to work right.
Later

well writing to a mounted floppy (/mnt/floppy) does not actually write to the floppy then and there.
Linux doesn't actually write to the disk until you unmount it (smart) - so that's prob why it's still got the light on..
not sure how that works with supermount, because if you manually unmount a floppy, it will write the data first, then unmount... but then supermount won't work next time..
and if u just eject the floppy, then it won't get to write the data ??

This is why I strongly suggest using the "sync" option for floppy mounts,
