As the topic says, when i mount the external hdd the ownership goes to root for some reason. Any reason why?

# Mass storage devices
/dev/sdb1 /home/hatten/Usb vfat users,exec,noauto 0 0
/dev/sdb1 /home/hatten/Xfs xfs users,exec,noauto 0 0

I can't understand those lines. What Filesystem are you actually using on your external HDD?
If it is vfat, that's normal behavior because it doesn't support modes and persmissions of files so it emulates owner - user who mounts it (don't know why root in your case, though) and permissions - 644.

hatten · 2010-01-06 10:58:45

It has XFS, the reason i got two lines is because i use them to mount different devices. When i plug in a usb stick with vfat, i use mount ~/Usb. When i mount my hdd i use mount ~/Xfs. I could exchange the last /dev/sdb1 to a uuid, but this was easier, and it works.

Maybe adding ck-launch-session in the xinitrc? Also off topic. how to you get a font to wrap to the bottom like in your terminal. i have a two line terminal but i can't get the fonts that you do... sorry for asking here! lol

My understanding is that the mount point is replaced by the root of the mounted file system. If the latter is owned by root:root, then that will be the ownership of the mount point.
I could see the same behavior with a standard ext2 partition (mount point was owned by root after mounting regardless of previous ownership), and ran a small experiment to confirm (mount; chown ... /mount/point; umount; mount). It worked as expected.

tomk · 2010-01-06 17:13:28

pmount is another option here.

How do I chown the root?

@jusebox, i have the default font, no clue what it is called cause I've no clue how to change it.

grey · 2010-01-08 09:27:26

How do I chown the root?

Become root; mount the partition /some/where; chown hatten:hatten /some/where; umount /some/where

Next time you mount it at /any/where; /any/where will be owned by hatten:hatten.

That works, thanks!
