[gentoo-amd64] mount by UUID

[gentoo-amd64] mount by UUID

[Bernhard Auzinger]

Hi,

I recently chose to mount my external hdd's by uuid. I just replaced the 
device file  (dev/sdxy) by the uuid (UUID=XXXXX...) in my /etc/fstab.

UUID=1ad24afc-f258-4b9e-a2c3-1e34c59562d8 /mnt/hdd_extern_1 reiserfs \ 
noauto,noatime,notail,user 0 0

UUID=1f0b0c58-7274-41c8-af00-2fbe5f4fbd6f /mnt/hdd_extern_2 reiserfs \ 
noauto,noatime,notail,user 0 0

As root I can mount and unmount the hdd's without any problem. But as user I 
can just mount but not unmount them. If I try to unmount them as user (after 
mounting as user, of course) I get a segmentation fault.

Maybe someone can give me a hint, what is going on.

So when you try to run `umount /mnt/hdd_extern_1` as a plain ole user
you get a segfault?  If that's the case then I'd say it's probably a bug
in either umount or libuuid.  Either way I'm sure the devs would be able
to help you if you file a bug.  You should probably include a backtrace
with your bug report.

That's exactly what happens.

Isn't libuuid a part of e2fsprogs?

Good idea :).

Thank you.

I exchanged the UUID=uuid_number with /dev/disks/by-uuid/uuid_number and now 
it works. That's funny.

I'd still like to encourage you to file a bug.  A segfault is not the
correct way of reporting user error. ;)

Yes you're rigth and I intend to do so. But I'm a little slow these days. 
There is so much fine weather and so much mountainbiking I have to do 
(because of the nice weather :) ) and so much rest I've to take (because of 
the intensive mountainbiking). I think it will take a few days until I'm able 
to file the the bug :D. But I will do it.
