Eh? Where are you getting your information?

We have the upload path and upload directory configuration variables for 
precisely those reasons. All you do is configure different paths for 
different wiki. There is no need to fiddle with symlinks or even 
multiple installations.

There is no need to duplicate maintenance directories. We have had the 
--conf= and --aconf= parameters for ages, passing --conf= alone is 
normally enough as LocalSettings.php normally sets the $IP which is used 
to find the AdminSettings.php. And on top of that as of 1.13 we have 
native support for the MW_INSTALL_PATH environment variable. Just set 
that and there is absolutely no issue with finding the location of files..

The best way of hosting multiple wiki is using a single installation of 
MediaWiki, and testing the domain to determine what wiki to use config 
for. For command line stuff you can make your LocalSettings.php 
understand a environment variable, or find a way to pass a option 
argument specifying what wiki to use.

Aside from that, I personally handle different versions of MW with 
different modifications because I do development. So I use a symlink 
based setup.

That's what my own install directories contain... Every last single one 
of those is a symlink. Half of them might not even be needed. The skins/ 
isn't used, images/ is a useless one as well, and there are symlinks to 
legacy scripts that mostly aren't needed.

Personally, I use symlinks because it allows me to run different setups, 
different configurations, and such on different wiki. It's good for 
development, but wiki farming fits the single installation model best.
