Save yourselves a lot of pain by going directly to 5.0. 4.x is a stable sytem, and unlikely to change interfaces out from under a developer. Not so, 5.x. It's much easier to get something working, pick a flag day, and do a port, than it is to try and track changes (I made this mistake when John Dyson was revving the VM system, when I did a FreeBSD port to the Motorolla PPC "PowerStack" systems, back in 1996). From personal commercial experience, *never* try to track a moving target, if what you are using the code for is as a platform for research and/or developement, rather than as an ends in itself. FreeBSD people seem to forget that the purpose of most FreeBSD users is not simply "to make FreeBSD better". 8-). -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
