[Pkg-utopia-maintainers] Bug#396811: prerm script calls /etc/init.d/avahi-daemon directly

[Trent Buck]

Package: avahi-daemon
Version: 0.6.14-2
Severity: important

>From the policy manual:

    Maintainers should use the abstraction layer provided by the
    update-rc.d and invoke-rc.d programs to deal with initscripts in
    their packages' scripts such as postinst, prerm and postrm.

    http://www.debian.org/doc/debian-policy/ch-opersys.html#s9.3.3

The script /var/lib/dpkg/info/avahi-daemon.prerm contains

    if [ "$1" = "remove" ]; then
        /etc/init.d/avahi-daemon stop || true
    fi

It should instead read

    if [ "$1" = "remove" ]; then
        invoke-rc.d avahi-daemon stop || true
    fi

This change allows sysadmins to use the policy-rc.d mechanism to
change postrm behaviour, which is particularly useful in chroots (to
prevent daemons being stopped or started).
