/etc/udev/rules.d/65-mdadm.vol_id.rules uses non-existent 'vol_id'

[Jamie Strandboge]

[Impact]

 * In Lucid, /etc/udev/rules.d/65-mdadm.vol_id.rules conffile was dropped, but not properly removed in the preinst scripts. Later a conffile removal was added, but it had a wrong file name.

 * Causes errors to be printed on boot.

 * The fix is to properly remove this conffile.... all the until next LTS.

[Test Case]

 * Install mdadm package in Hardy, upgrade to precise, observe that the conffile is not removed.

 * Upgrading to raring/SRU'ed package should remove this conffile.

[Regression Potential]

 * Minimal as the conffile in question should not be used at boot.

[Original Description]

After upgrading a server from 10.04 to 12.04 I saw errors on boot about udev trying to use a non-existent vol_id:
failed to execute '/lib/udev/vol_id' 'vol_id --export /dev/md0': No such file or directory

I tracked this down to the following line in /etc/udev/rules.d/65-mdadm.vol_id.rules:
IMPORT{program}="vol_id --export $tempnode"

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=541884 mentions this issue and says that we should be using '/sbin/blkid -o udev -p ...' instead. Indeed, checking /lib/udev/rules.d/64-md-raid.rules, it has:
IMPORT{program}="/sbin/blkid -o udev -p $tempnode"

I then updated /etc/udev/rules.d/65-mdadm.vol_id.rules to use this instead, and the errors went away.

Hmm....
That rules file should not be present on precise and up since precise-release (as in the original 12.04.0) removes that conffile:
rm_conffile /etc/udev/rules.d/65_mdadm.vol_id.rules

Is that file still present on your system? it should have been removed on upgrade...

I haven't yet checked upgrading a 10.04 -> 12.04, and making sure the upgrade is correct. This is a next on todo.

[Jamie Strandboge (jdstrand)]

I still have this file. This was an upgrade from 10.04 to 12.04.

[Dimitri John Ledkov (xnox)]

I am suspecting your system may have a few other obsolete conffiles. My default test VM ended up having 14 obsolete conffiles. For this issue I have further filed bug 1160502 to hopefully address in the do-release-upgrader itself.
