It's been a while since I did this, but, if I recall correctly, Debian
generates a `snakeoil' key+certificate when the "ssl-cert" package
is installed, and other packages that want a key and/or certificate
(like Postfix) Depend on the ssl-cert package and just use its
`snakeoil' by default until the sysadmin goes in and reconfigures them
to use something better.

cf. /var/lib/dpkg/info/ssl-cert.postinst and /etc/postfix/main.cf.
