hi

Gentoo udev Guide didnt answer my question, is it good idea to remove fstab 
entry for removables, i have this 
/dev/hdc          /media/cdrecorder       auto    user,exec,noauto,managed 0 0
since fresh install and then there was devfs. Am I right that udev will handle 
mounts for /dev/hdc/ (DVD+CDRW) according to udev.rules what media is 
inserted?

And is there way to very force umount media even if it claims device is busy 
and i cant figure out what process is responsible for that.

No, udev handles device node creation. You still have to mount yourself or 
use an automounter.

Did you try fuser?

I made the experience that fuser or lsof often don't help much when you 
have problems unmounting a device. The output is empty, and you don't 
know why the heck you are not allowed to unmount a device.


Best regards

fuser -k /media/cdrecorder was successful, thanks for pointing to fuser

will the -k option also help if a kernel lock happens on a device?


Best regards

Also try:

ls -l /proc/[0-9]*/cwd.

udev handles the creation of the device nodes, mounting is handled by
hal. hal normally creates its own mount points in /media, but if the
device is listed in /etc/fstab, it will use whatever is in there.

How do you know that mounting is handled by hal on his machine? He didn't 
say so. He could also use the kernel automounter to create /media/whatever.

Fair point, but either way, it is not udev doing it and /etc/fstab is not
involved.
