Most of the server owners on our virtualmin install are limited to 1 database.
Naturally, I had a user who wants to create 2 instances of mediawiki. This isn't possible because the installer assumes the table prefix is always "mw_".
It would be nice to specify the table prefix, of course, so users limited to 1 db could have multiple instances of mediawiki.
I'd be willing to take a crack at the script if you like. It doesn't look too tough to add another config parm to the perl. The only thing that I'd need help with is figuring out what the current db prefix is (so we can make the conflict check work).
Also, it would be useful to have a brief overview of how this gets run. It's clear it gets included from somehwere, and I might want to check out some of those subroutines if I run into a bug.
