Comment 2 for bug 441796

This was no fun when I tried to recover from cryptsetup breakage yesterday. The telinit in upstart's postinst causes the machine to reboot under Ubuntu's debian-installer, when run from its rescue prompt. So either ubuntu-installer should guard itself against this usage of "telinit u" to re-exec init or upstart should not invoke it unconditionally. I never experienced reboots during dpkg's --configure run before.
