[Pkg-systemd-maintainers] Bug#721244: Use command line parameter instead of env var for purging a service

[Michael Biebl]

Package: dh-systemd
Version: 1.8
Severity: normal

dh-systemd generates that sets _DEB_SYSTEMD_HELPER_PURGE=1 in postrm
which modifies the behaviour of "deb-systemd-helper disable"

I think it would be nicer, to use an explicit verb for that special
cleanup, i.e. "deb-systemd-helper purge".

The postrm code would then look like this:

if [ "$1" = "remove" ]; then
	if [ -x "/usr/bin/deb-systemd-helper" ]; then
		deb-systemd-helper disable foo.service >/dev/null
	fi
fi
if [ "$1" = "purge" ]; then
	if [ -x "/usr/bin/deb-systemd-helper" ]; then
		deb-systemd-helper purge foo.service >/dev/null
	fi
fi
