When I boot I get a requester saying that this copy of PFS-2 is invalid.  Why ?

This message appears if an unregistered PFS2 is started. PFS2 is registered by installing it using the install script on the CD. Directly copying the filesystem from the CD to the RDB does not work and will result in this error message.

If you have this problem you have to replace the old filesystem you used on the partition in order to make it functional again. Please follow the following steps to achieve this :-
