# shill termination may take more than 5s (the default kill timeout) in some
# cases (e.g. it needs to disconnect a cellular modem from the network). A
# longer kill timeout is used to ensure that shill terminates properly in most
# cases. Also, stop shill on "starting pre-shutdown" so its exiting blocks the
# chromeos_shutdown script from running (jobs that "stop on stopping
# boot-services" may still be running in parallel with chromeos_shutdown if
# they do not exit quickly).

# HEADS UP!  'expect fork' is usually a loser when used with
# 'script'.  Unfortunately, shill needs 'expect fork', and
# we need a script to figure out command arguments at run time.
#
# To avoid confusing Upstart, the script below can use only shell
# built-in operations until it gets to the 'exec' at the end.  Any
# command that causes the shell to fork/exec a subprocess is a
# no-no.
