Yes, but if you look at my 4 to 5 upgrade procedure in detail you will see that it isn't just a straight-forward "build from source" approach. It actually uses a rather strange but necessary "overwrite the running system with new binaries and then rebuild from source" approach. And I'm still not seeing why this wouldn't work for a direct 4 to 6 upgrade. This upgrade approach is far away from being pretty and elegant, of course. But it allows one to fully remotely upgrade a FreeBSD box without access to the console and single user mode (which was the hard problem I had to circumvent). And I still think it could be adapted for a direct 4 to 6 jump, although I cannot recommend doing this approach if it can be avoided. > But in general for such a "large" upgrade I'd strongly urge backing up > all data, wiping the disk(s), and reinstalling + restoring.

Sure, at least if someone wants UFS2 this is the only possibility at all AFAIK... -- rse@FreeBSD.org Ralf S. Engelschall FreeBSD.org/~rse rse@engelschall.com FreeBSD committer www.engelschall.com
