[Intrepid] boot failure: by-uuid symlinks not created

[Mathieu Bérard]

Binary package hint: dmsetup

Hi,
since update to dmsetup 1.02.25-1ubuntu1, logical volumes are not symlinked anymore to /dev/by-uuid causing mount by-uuid failure at boot time.
the culprit is in the 65-dmsetup.rules udev script at line 20:

"ENV{DM_TARGET_TYPES}=="|*error*", GOTO="dmsetup_end"

the string seems to always match resulting in a bogus goto to the end of the script skipping the /dev/by-uuid symlink creation.
Commenting the offending line workaround the problem.

Could you run dmsetup --export on each of your dm devices and provide the output

DM_TARGET_TYPES appears to be missing - Martin?

Merge error, taking.

   * debian/patches/dmsetup-export.patch: re-add DM_TARGET_TYPE exports,
     required for detecting state of dm devices during udev rule execution
     and sane creation of by-uuid symlinks (forwarded to Debian #486780).
