[gentoo-user] chown - not permited

[gentoo-user] chown - not permited

[Joseph]

I mount USB stick form camera and I can not change ownership (I'm login as root)

drwxr-xr-x 9 root root 32768 Nov 18  2013 DCIM
-rwxr-xr-x 1 root root     4 Nov 21  2013 _disk_id.pod
drwxr-xr-x 2 root root 32768 Aug 14  2013 LOST.DIR

I can read and write another USB stick but others I can not.  How to control it?

What filesystem does it contain and what mount options are you using?
Depending on the filesystem it can be possible to mount with
user/group permissions.

One USB stick was ext2 the other was dos file system.  I have problem with dos.
I have commentd out in fstab:
/dev/sdb1		/media/stick	auto    	noauto,rw,user        0  0

and let udisks mange it.  It works.
Except that now I have ugly long names, for ext2 I get:
/run/media/joseph/2f5fc53e-4f4c-4e74-b9c4-fca316b47fea

for dos I get:
/run/media/joseph/3136-3934

with fstab entry they all were mounted under: 
 /media/stick

Those long names are filesystem id's and volume labels. You didn't tell
udisks what to call the mount point so it has picked the only thing it
has available - the ID of the filesystem.

fstab is a really bad tool for this, it does not apply the rules to your
USB sticks, it applies them to anything that just happens to get node
/dev/sdb1. Don't assume that will *always* be a portable usb stick,
because it won't.

Read the udisks documentation to find out how to customize naming of
mount points.

FAT32, the DOS fs, does not have ownerships. You cannot change something
that isn't there.

In the begining, there was nothing.
And God said "Let there be light" and there was light.
There was still nothing, but you could see it better.

Joseph.

If you give the filesystem a Label. Then udisks will use that instead of the UUID string.

Thanks.
What is the best way to edit USB Label?

$ apropos label
e2label (8)          - Change the label on an ext2/ext3/ext4 filesystem

I think you may be able to give DOS filesystems a label at creation time.

For the DOS filesystem, mlabel, part of sys-fs/mtools.

Or "fatlabel", from sys-fs/dosfstools.

Thanks, I've tired mtools "mlable" couldn't get it to work.
"fatlabel" worked perfectly.
