For what its worth, I have a single SCSI disk to boot multiple FreeBSD versions, 3.0-current on this first slice, 2.2 on the second. I boot the first slice's FreeBSD as usual with sd(0,a)kernel You don't need a specially configured kernel for this version/partition. The second one is booted like this sd(0,s2a)/kernel-2.2 -r This FreeBSD version has a kernel configured with "root on sd0s2a" as "/kernel-2.2" on partition sd0s2a AND on the same name on sd0a with is the same as sd0s1a for me. The kernel is always loaded from sd0a/sd0s1a, but you need a copy of it in sd0s2a as well for userland programs that need to read to read the kernel image. You need "-r" to use a root partition that is not the one the booted kernel lives in. booteasy will ask you for a slice to boot from, it doesn't matter what you choose, since kernels are loaded from the first BSD slice in any case. Hope this helps, let me know if not. I missed the original posting and don't have the CC: line, could someone please forward this to whoever had the original problem? Thanks.
