I have updated an 8.2 system with the "latest rc3" ;-)
Installation process was ok, but there is a problem with devfs. Devfs is
loaded without error, but whenever a process try to access to /dev/hdax or
/dev/ttyx is not able to do it. With devfs=nomount the system starts well.
I will try to play more with this problem this afternoon if I can get time...
