Another quick update: If you're doing the multiple linked wikis/wiki family with shared resources on one droplet as described here, do not symlink the 'includes' folder. This one needs to remain independent in each of your separate wiki install folders. If it's not, an update to one crosses over to all of them. (Don't ask me why, because I don't know. It says you can do this, and, well, you can't without it glitching up, at least with 1.31, and before anyone else tears their hair out, well... there you go. I left serialized and vendor alone as well, and it's keeping the installs properly distinct.)
