AutoMounting / Udev and HAL

Mac Tzu · 2009-08-09 11:51:51

Hey fellow Archers,

Sorry if this is a bit of a Noob Question.

But I am having issues with automounting usb drives that etc.
I am running eeepc 1000 and everything works fine out of the box. But I have shown Arch to a friend of mine and we can't gain access to the usb drive with free.desktop permission error. I have read the wiki and forum posts. However I have found the are for much older versions of HAL and Udev, and they are contradictory.

Please if you could help me clarfiy a solutions. Should Udev handle to mounting and permission rule or should I add HAL policy ?.
If HAL if the best solution could be so kind as to provide a example of Hal policy as my previous attempt to edited HAL has failed.

Kind Regards

Mac Tzu

That may help you

Make sure you are member of storage group and you start your WM with "exec ck-launch-session openbox" in .xinitrc for example (GDM/KDM does this automatically).

*sigh* whatever happened to the 'old', trusted *nix way?
Why not just manually mount/umount it ?
Why the heck should we copy all windows' mannerisms?

well, it's much easier just to plug-in USB and browse than manually mount it.

perbh · 2009-08-14 18:49:07

oh?
sudo mount /dev/sdX1 /mnt/usb
sudo umount /mnt/usb

That doesn't look like a lot of work to me - and in addition, you _know_ what you are doing and after doing a 'umount' you _know_ not to pull the thing out until you get the prompt back. I have seen too many broken fs's because people have pulled out the stick before it was ready!

If you look at the postings in this forum - a disproportionate amount deals with automount (and unmount) - it's just not the *nix way!

I disagree with perbh. I wouldn't want to use mount or pmount for every external drive I plug in.
