Hi,
I just installed MediaWiki from cvs relatively painlessly, upgrading from
1.2.5 and following Brion's suggested path.
I ran into a couple of minor issues, which should at least be noted in
INSTALL.
First, the username that I use to access mysql is not root, so I had to
change index.php manually to fix that.
Second, I had to do a manual copy of the uploaded files from my previous
installation into /phase3/images.
That's it!
Thanks a lot for developing this software.
