Merge lp:~lool/ubuntu/saucy/lxc-android-config/set-display-mir into lp:ubuntu/saucy/lxc-android-config

[Loïc Minier]

Add set-display-mir boot-hook to create .display-mir file on boot, unless the hook already ran; switches the default to Mir for users of SF on system-upgrades; this should only run once on upgrades, but the current boot-hooks don't allow this with a dep on other jobs.

[Loïc Minier (lool)]

Tested by booting without .display-mir, it got added along .set-display-mir-done and Mir was used.

Then removing .display-mir + rebooting, and SF came up.

XXX not sure if this is a placeholder for a bug or something

review: Approve

[Loïc Minier (lool)]

XXX is indeed for a boot-hooks bug that we can't listen for "new-version", only for "every-boot" which is suboptimal, but works.

Only touch .display-mir on supported devices: grouper, maguro, mako.
