# Set up ofono to run with the phone simulator. This uses an unshared tmpfs
# mount over /etc/ofono/ to avoid having to modify the file system.  The script
# can either be invoked without arguments and run until Control-C, or run a
# program (with arguments), in which case everything will be restored when the
# program ends.
