I can't answer that. I built my two-BSD hd from sources and installed that way. > Then, will, bootEZ will see both FreeBSD partitions, and allow booting > either? This I haven't found an answer to. It should see them both, but it will label them both as "FreeBSD". I installed Grub so I could label them as "FreeBSD Current" and "FreeBSD Stable". > > Furthermore, can either then mount the other slices' partitions? > I cannot see why not, unless trying to write to ad0s1 from ad0s2 screws > up due to ad0s1 having DIRPREFS and ad0s2 not? Anyone? No problems at all. You can even have them both use the same swap partition to save a little space. > Is it really this straight-forward, the "Just do it" Nike approach? Except for sysinstall, the answer is yes. I suspect the answer is yes for sysinstall as well. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
