The same behaviour occurs with udisks-2.0.0 as shipped with openSUSE 12.3 and a self-compiled udisk-2.1.0. I also tried an Ubuntu 13.04 LiveCD with the same result, so it's not openSUSE specific. wolfi@amiga:~> cat /etc/fstab /dev/sdb2 swap swap defaults 0 0 /dev/sda1 / reiserfs acl,user_xattr 1 1 proc /proc proc defaults 0 0 sysfs /sys sysfs noauto 0 0 debugfs /sys/kernel/debug debugfs noauto 0 0 usbfs /proc/bus/usb usbfs auto,busgid=110,busmode=0775,devgid=110,devmode=0664 0 0 devpts /dev/pts devpts mode=0620,gid=5 0 0 /dev/sdb1 /windows/C ntfs-3g defaults 0 0 wolfi@amiga:~> rpm -q udisks2 gvfs libatasmart4 udisks2-2.0.0-5.4.1.x86_64 gvfs-1.14.2-2.1.2.x86_64 libatasmart4-0.19-2.1.1.x86_64 Reply at: https://bugs.launchpad.net/ubuntu/+source/udisks2/+bug/1064195/comments/2 ------------------------------------------------------------------------ On 2013-04-23T17:09:29+00:00 Wbauer wrote: Created attachment 78382 output of 'udevadm info --export-db' (as root) Reply at: https://bugs.launchpad.net/ubuntu/+source/udisks2/+bug/1064195/comments/3 ------------------------------------------------------------------------ On 2013-04-23T17:10:44+00:00 Wbauer wrote: Created attachment 78383 output of 'cat /proc/self/mountinfo' Reply at: https://bugs.launchpad.net/ubuntu/+source/udisks2/+bug/1064195/comments/4 ------------------------------------------------------------------------ On 2013-04-24T18:11:05+00:00 Wbauer wrote: I just noticed that the floppy _is_ mounted as user when I specify the filesystem type with the -t option: wolfi@amiga:~> udisksctl mount -b /dev/fd0 -t vfat Mounted /dev/fd0 at /run/media/wolfi/disk. wolfi@amiga:~> ls -la /run/media/wolfi/disk insgesamt 86 drwx------ 2 wolfi users 3584 1.

Well, we can't identify it ahead of time as it would create a lot of noise and there's no way to check if a new medium has been inserted. We should probably special-case /dev/fd* and always just assume that it's vfat...

Aha. Thanks for the explanation, makes sense. > We should probably special-case /dev/fd* and always just assume that it's vfat... Yes, I think that would be the best thing to do. As it is now, you can't really use the floppy drive in graphical environments like KDE and GNOME, although they do have a nice floppy icon in their filemanagers...

Ext4 partitions are just used on internal disks, they can be used on external ones too.

And this is why: $ ls -lh /run/media/r3pek/ total 8.0K drwxr-xr-x 4 root root 4.0K Jul 3 17:55 6ef9a3f5-26fc-41eb-baa8-1f344b419725 drwx------ 7 r3pek users 4.0K Dec 31 1969 7E11-ECF4 Permissions should be enforced when creating the mountpoint, so that the owner of that directory is the user who requested the mount. Of course this should only be done for removable harddrives to prevent the user to mount the local filesystem and change anything in it.

We should > probably special-case /dev/fd* and always just assume that it's vfat... What about trying to identify it, directly before the mount? Or is that what you meant anyway?

This seems to be a regression, where udisks wouldn't try to mount filesystems as the calling user first. This can be tested with any entry with the user keyword and a fat filesystem. In my case an usb dongle. UUID=10B3-837F /media/cruzer vfat rw,nosuid,nodev,relatime,user,showexec,utf8,errors=remount-ro 0 0 Mounting the device with udisks results in the filesystem mounted as root. I've attached a patch to fix the problem. Please review.
