su is at best unnecessary, it does not offer anything that start-stop-daemon
can't do. At worst it causes problems.
su always wants to access /etc/passwd and /etc/shadow, in SE Linux the startup
scripts are not allowed access to /etc/shadow and thus su fails.
Also while we're at it, postinst scripts should not directly start a daemon
they should always call the script in /etc/init.d so that if the
administrator has changed the daemon startup process then those changes will
be respected at upgrade time.
