There were a number of problems with /etc/pam.conf compatability and OpenSSH v1 vs. v2 and already generated certs needing to be regenerated as a result, last time I went back to 4.x from a 5.x. The MAKEDEV problem is more pronounced moving from -current, since -current has devfs. My recommendation would be *against* using "makeinstallworld", since with a CDROM approach, the devfs isn't mounted on /dev, so the devices get made correctly (devfs would also throw a wrench into the NFS mounted CDROM approach I talked about before; sorry). As I said before about boot blocks: all bets are off: I have no idea whether or not they are capable of booting older versions of the code correctly any more; there have been some recent problems because of some changes, and because of a bzero that Alfred was rumored to have lost from Jon Mini and James Harris' contributions toward an updated FORTH-based "nextboot"... ;^). -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
