Subject: Failure in 0.6 release

Sync'ed up 0.6 with devel@r1831 since we were in TRAINCON-0. Everything
built successfully.

Using image #179 with 0.6, mir itself works (i.e. mir-demos & nested), but
USC has the following error :

*root@ubuntu-phablet:~# cat /var/log/lightdm/unity-system-compositor.log*
*Unknown command line options: --vt 1*

The "vt" option is passed in by the wrapper in lightdm, but not sure why
usc is rejecting it. Without 0.6, usc works fine with the same set of args.

It'd be nice if the AUS, or EUR can take a look on Mon. Follow the
instructions (updated due to platform versioning) below to install and test
:

Have a good weekend.

Hm. I can't reproduce any part of this (although, as always, 
verification would be easier if we did any logging at all!).

unity-system-compositor from 0.6 works fine (on image 181). For me, 
LightDM doesn't pass the --vt option to unity-system-compositor. The 
relevant change would be r1826 on lp:mir/devel, which now means that 
we'll reject unknown commandline options by default.

BTW, I've been maintaining branched bugs tasks to match up with the 
actual point where the code was branched (tag "br0.6" in devel == r1806).

So any fixes that land on devel after r1806 should have two separate 
tasks: 0.6 and 0.7, to accurately represent where and if a fix got 
applied to each branch. Often a fix only exists in one branch and not 
the other, so it's important to represent that in the bug and not get 
caught out by unexpected regressions later.
