@Tony, right, upstart uses the original environment when re-starting
after a crash.

The command line if you want to start/re-start ofono using upstart is:

# stop ofono
# start ofono OFONO_RIL_DEVICE=mtk OFONO_RIL_NUM_SIM_SLOTS=2

or

# restart ofono OFONO_RIL_DEVICE=mtk OFONO_RIL_NUM_SIM_SLOTS=2

Title:
  [krillin] Restart ofono, cause repeated crashes in ril plugin

Status in “lxc-android-config” package in Ubuntu:
  Invalid

Bug description:
  On krillin, if ofono is restarted on the command-line, or crashes and
  restart, it will repeatedly crash in the ril plugin's
  ril_radio_state_change() function, as the environment variables used
  to communicate the ril device-type and number of SIM slots are
  replaced by the values in the upstart override file for ofono ( which
  the env vars to 'ril' and 1 respectively ).

  This means that the rildev plugin loads the wrong ofono device plugin
  ( ril instead of mtk ), which then repeatedly asserts when it gets
  back a garbage radio state change unsolicited message from rild.

  Program received signal SIGABRT, Aborted.
  0xb6d8e8e6 in ?? () from /lib/arm-linux-gnueabihf/libc.so.6
  (gdb)

  This was reproduced on krillin rtm #94.

  I *think* the correct fix is to change the env statements in the ofono
  override job to leave off the assignments:

  env OFONO_RIL_DEVICE
  env OFONO_RIL_NUM_SIM_SLOTS

  ...and then in rild.conf, if the respective android properties aren't
  set, use the defaults previously set in ofono.override.

  Note, I've only reproduced this via the 'restart'.  I haven't verified
  that an ofono crash and respawn behaves the same, but I'm pretty sure
  it does.
