ok, it appears it wont work without udev, got around that.
However, I can make cachefilesd die constantly with this error
Failed to stat directory: errno 75 (Value too large for defined data
type)
blade12_ROOT:/home/helix/cachefilesd-0.8 # ./cachefilesd -s -n
About to bind cache
Bound cache
Daemon Started
Scan complete
Refilling cull table
