Well, since it's not, we don't have to worry about it.

If you really want to check for shell aliases and functions,
you could do this instead.

#!/bin/sh

err=0

invoke-rc.d package <action> || err=$?
case "$err" in
	(12[67])
	/etc/init.d/package <action>
	;;
	(*)
	exit $err
	;;
esac


As a third option, you could change Debian policy to require conformance
with "SUSv3 + echo -n + command -v".
