Comment 37 for bug 1387214

after running with the change for one week on my krillin i must say that i dont really see any performance impact or any other bad behavior from the change ...

it would be nice to have some upstart job that at least does an emergecy readonly mount on shutdown/reboot like we plan for adbd "adb reboot" by echoing "u" into /proc/sysrq-trigger ... that way we would at least be sure we do not unmount dirty and calling this command takes close to no time.
