[Bug 875636] [NEW] usbmount doesn't auto-mount external harddrive anymore in oneiric

[Launchpad Bug Tracker]

[Impact]
usbmount doesn't auto-mount external hard drive in Oneiric. This is considered a regression as it used to work in natty.
usbmount relies on /sbin/blkid to determine the file system type. blkid output is different in Oneiric and the regex fails to catch the file system type.

[Development Fix]
This was fixed in Debian package 0.0.22 and is meanwhile sync’d to Precise.

[Stable Fix]
The attached patch back ports the fix from Debian.

[Test Case]
Please see original report below.

[Regression Potential]
The patch itself is relatively small and unlikely to introduce regression.

[Original Report]
$: lsb_release -rd
Description:    Ubuntu 11.10
Release:        11.10

$: apt-cache policy usbmount
usbmount:
  Installed: 0.0.21
  Candidate: 0.0.21
  Version table:
 *** 0.0.21 0

usbmount uses '/sbin/blkid -p /dev/sdb1' to determine the filesystem
type. It seems that the output of blkid changed from natty to oneiric:

natty:
$:/sbin/blkid -p /dev/sdb1
/dev/sdb1: UUID="ff3637e4-2a20-4a81-a276-93bea80e1bfa" VERSION="1.0" TYPE="ext3" USAGE="filesystem"

oneiric:
$:/sbin/blkid -p /dev/sdb1
/dev/sdb1: UUID="ff3637e4-2a20-4a81-a276-93bea80e1bfa" VERSION="1.0" TYPE="ext3" USAGE="filesystem" PART_ENTRY_SCHEME="dos" PART_ENTRY_TYPE="0x83" PART_ENTRY_FLAGS="0x80" PART_ENTRY_NUMBER="1"

The regexp in

FSTYPE=$(echo "$DEVINFO" | sed 's/.* TYPE="\([^"]*\)".*/\1/g;
s/[[:blank:]]*//g;')

triggers on PART_ENTRY_TYPE which finds '0x83' as file system type and
prevents it from being mounted.

Attached patch fixes this for me.
