+ [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 was a bit late, as dpkg no longer new
+ which package that conffile belongs to and hence the preinst script has
+ not removed this file for people that upgraded since Hardy.
+
+ * 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.
