Temp files and symlinks

[Will Newton <will@xxxxxxxxxxxxxxxxxxxx>]

In my persistance storage directory (/dev-state) I get some temporary
files. I would be grateful if someone could tell me if they should be
there or not. They are of the form:

dri-temp-1002

and

fd0u1040

relating to DRI and floppy drivers respectively.

Also symlinks are stored, which seems pointless as they are created by
devfsd, and when I change the config I want them to disappear.
