Is it straightforward to > installworld/mergemaster to somewhere other than / ? That is very well doable. On boot you can interrupt the boot process by pressing space an set another location for the kernel. More information is here. http://www.freebsd.org/doc/en/books/handbook/boot-blocks.html The rest is just about files. After you copy everything in ad0s1b (with a fs in it) you can boot from ad0s1b:/boot/kernel. I think you can do something like make installkernel DESTDIR=/blabla, but I'm not sure. Maybe more easy is booting with a LIVE-cd. Than you can mount everything needed for installworld in /mnt/tmproot, so you get: /mnt/tmproot mounted the _new_ / partition (ad0s1b?) /mnt/tmproot/usr where /usr is mounted (ad0s1a) /mnt/tmproot/var where /var is mounted (ad0s1e) Do a chroot /mnt/tmproot and than run installworld and mergemaster as usual from /usr/src. Don't forget to make a backup. It is on your own risk. ;-) Ronald.
