I would prefer a documentation how to generate the password (possibly with a stronger hash on modern systems).
mkpasswd can be used. Document an example call in the schema or in elbe preprocess's manpage.
Maybe recommend whois (which contains mkpasswd) on the elbe package.

If you want to leave that to me, I am okay with that.
Thanks for your work on this!
