I have a running farm with dokuwiki. The media manager (file upload)
part is the only broken one. The farm is using a common lib/ and
inc/. conf/ and data/ are specific to each instance in the farm, and
I only needed to copy the root doku.php file to each instance. Thus
creating a new instance of a wiki inside the farm consists in:
- creating a directory
- copying doku.php to it
- symlinking inc/ and lib/
- creating and populating conf/ and data/
I've set up a small demo on: http://isis-ulp.org/bug/farm
Drawback: lib is common, so plugins and templates too.
Advantage: except doku.php everything comes from a single (father)
instance of dokuwiki, so upgrades are easy.
The change to the code was very light (one line patch attached to
this message). I have not investigated further on the media manager
problem and haven't tested much so I don't know what else could be
broken.

Farming with separated directories allows to imagine a plugin which
could create what's necessary to run a new instance of a wiki in a
farm.

I tried to avoid that, creating completely separated directories to
host each instance of the farm. Keeping all config files together
would be smarter. My first attempt was as yours, playing with the
$conf['basedir'], $conf['baseurl'] and $conf['savedir'], but I
failed.

What inside lib/ would be specific to a wiki instance? plugins and
tpl... anything else ? Could $conf['template'] and $conf['plugins']
(this one is to be created) point to additional content specific to
a wiki instance of the farm?
