At home I performed dump, newfs, and restore using a staged approach to other disks or in one case to another partition on the same disk to avoid backing up to tape. (Musical partitions anyone? :) ) It took about 3.5 hours and eight reboots to do four machines. Most of the 3.5 hours was spent reading, watching CNN, CNBC & CBC/NW, and making a quick trip to the store while data was being moved about -- quite a painless experience. :) At work, I don't have the luxury of doing a wholesale conversion as all the machines have one disk and most have only one partition. I've been toying with the idea of duplicating up /bin for example to /bin.new, booting into single user state during a change window and mv /bin /bin.old && mv /bin.new /bin && rm -rf /bin.old (not exactly but you get the idea). Given that the cylinder groups are not in a virgin state, I'm beginning to think that this approach may be less optimal than what I might expect. In the mean time I've done a make release which includes all of my personal patches to FreeBSD. Besides serving as a DRP recovery starting point, backing up my data and configs (/etc, /var, etc. [no pun intended]) installing from the release I just made and restoring the data might be the best solution. It will probably take less time than the musical partitions I played when converting my four systems at home but require more hands on work.
