[Logcheck-devel] Bug#249324: gratuitously recreates logcheck user

[Aaron M. Ucko]

Package: logcheck
Version: 1.2.20
Severity: important

For some reason, logcheck.preinst unconditionally deletes and (re)adds
the logcheck user.  This can have the effect of changing its uid,
which is problematic if cron has cached the old uid (as I have
observed it to do).

Please conditionalize that code on upgrading from versions prior to
1.2.19:

case "$1" in
    install|upgrade)
	if dpkg --compare-versions "$2" lt 1.2.19; then
	    ...
	fi
	;;
esac

The postinst's chown/chgrp/chmod calls should probably also be
conditional to support admins who want somewhat different setups for
whatever reason.  (I don't happen to, but I can imagine some might.)
