[ Clint Byrum ] * do not run 'telinit u' on upgrade, as this will break upstart. touch /var/run/init.upgraded instead, which will force a re-exec just before remounting root read-only. LP: #672177, LP: #694772.
[ Matthias Klose ] * Call locale-gen --purge when updating from eglibc-2.11.x. LP: #504198.
