Though this is true, I discourage You to upgrade a running system. I
tried to upgarde 5.3-RELEASE to 5-STABLE without booting to single user
mode. I simply sent a TERM signal to most of the processes, and tried to
make installworld. There was some error messages, the system crashed and
didn't boot anymore...
