Hello pfloor.
I know very well the wiki page, because I have created.

About the command you have suggested, only work for db keys that already in the configuration files, but not for keys in the template files. Not all posible db keys are in db conf files as default. One example:
DisableAnonymous in /etc/e-smith/templates/etc/proftpd.conf/50AnonymousPrimary
If you run
db configuration show, you can't see this variable, but exist in template file, and apply only when you have set in the db conf file.
Also, I have found some variables in db file without proper template file to expand.
The real way to know what variables exist, is to open one by one each template file, and see if has a perl sentence to expand.
I don't know if you can understand my BAD english.
