shellcheck v0.7.1 complains about a bunch of issues:
SC2154: status is referenced but not assigned.
SC2181: Check exit code directly with e.g. 'if mycmd;', not indirectly with $?.
SC2207: Prefer mapfile or read -a to split command output (or quote to avoid splitting).
SC2235: Use { ..; } instead of (..) to avoid subshell overhead.
SC2236: Use -n instead of ! -z.
The "$status" variable disappeared in d4763aba14.
The init scripts of ngcp-rtpengine-daemon and
ngcp-rtpengine-recording-daemon had a logic bug, where a failing stop
action didn't properly return, but continued execution of the following
firewalling code (ngcp-rtpengine-iptables-setup). Thanks to Guillem
Gover for spotting this one. While at it, no longer execute under
'set -e'.

This makes it difficult to interpose local scripts to override local
behavior, for testing purposes for example.
