radius 5071a33cd3 simplify this mess
So this makes two basic changes:
1. Add a few extra dirs, hide root dir in the filesystem
2. Simplify the default dir selection code so it doesn't take three code blocks to change a dir

A few of the decisions here were weird.
This shouldn't affect anything for end users and makes the code more mantainable.

Log from the first run:
