But I should be able to boot my ZFSv14 root pool using the ZFSv15 build = of FreeBSD, correct? But the problem scenario would be when I've = upgraded by root pool to v15 and I attempt to boot it with v14 boot = loader. At least that is what I think ... I guess what I'm getting at is ... you should be able to buildworld, = installkernel, reboot, installworld, reboot without worry. But when = after your run 'zpool upgrade', you will need to re-write the bootcode = using gpart on each of your root pool ZFS disks. Am I understanding this correctly ? Thanks for all the work on ZFS BTW, it's great!
