Bug Description

With udisks in quantal, when inserting a USB disk I see the following mount:

/dev/sdb1 on /run/media/vorlon/BB3E-80C3 type vfat (rw,nosuid,nodev,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,uhelper=udisks2)

Quite aside from the questionability of these mounts being under /run/media when that's precisely what /media exists for per the FHS, the disk is mounted without the 'user=vorlon' option. As a result, I can't run 'umount /run/media/vorlon/<tab>' as a non-root user. It seems that the only way to unmount it as a user is to use the special 'udisksctl unmount' helper.

Dropping compatibility with the historical commandline interfaces is unwarranted. Please fix the missing mount option so that 'umount' still works.

udisks1 did not use the "user=" option either. It's supposed to call /usr/sbin/umount.udisks2, similar to /usr/sbin/umount.udisks from udisks 1, through the "uhelper=udisks2" option. Explicitly calling "umount.udisks2 /dev/..." works fine. I'll investigate this.

summary: - udisks in quantal mounts disks without 'user=' option, prevents user
- unmounting
+ "umount" for udisks2 mounted devices does not work

Aah, easy: umount.c does

                sprintf(umountprog, "/sbin/umount.%s", type);

but umount.udisks2 is installed into /usr/sbin/. I'll fix this.

This bug was fixed in the package udisks2 - 1.99.0+git20120919-1

udisks2 (1.99.0+git20120919-1) experimental; urgency=low

  * Update to current upstream git head:
    - configure.ac: raise gudev dependency
    - Update list of recovery/system partitions
    - Add support for creating exFAT filesystems and changing exFAT labels
    - Add textual descriptions for IMSM Raid members
    - Use all-caps for RAID in descriptions
    - Lots of test suite robustifications and added tests
    - Enable large file support (LP: #1039022)
    - Mount vfat with "flush" option
  * Drop 00git_dev_t_annotation.patch, 00git_testsuite.patch.
  * debian/control: Bump libgudev-1.0-dev build dependency as per upstream
  * debian/udisks2.install: Install umount.udisks2 into /sbin; our old
    util-linux version does not yet find it in /usr/sbin/. (LP: #1019651)
