* Go back to using the backgrounded reboot command as we had before 3.14. Just calling "reboot" is prone to hangs and timeouts in case reboot is too fast and shuts down our communication channel. * Fix --override-control option in adt-run(1). (LP: #1453495) * Fail with an error if --override-control file does not exist. (LP: #1453503) * ssh-setup/snappy: Add -b/--show-boot option to direct boot and console messages to stdout. (LP: #1453154) * adt-virt-qemu.1: Document --show-boot option. * Add test case for using a @ command line include file for a virt runner. * Strip leading and trailing space from argument lines in '@' included command line argument files. (LP: #1453498)
