Dmitrijs Ledkovs has proposed merging lp:~xnox/upstart/rebootcmd into
lp:upstart.
Requested reviews:
Upstart Reviewers (upstart-reviewers)
For more details, see:
https://code.launchpad.net/~xnox/upstart/rebootcmd/+merge/149619
Useful for nexus7 to execute: reboot -f bootloader, such that one is back into
fastboot mode.
I'm planning to cherry pick & upload into ubuntu package, as this is needed for
automated QA testing of nexus7 images.
