I've got a couple FreeBSD 7.0 systems which I am trying to upgrade. I had used ZFS for everything except the boot where I had used a gmirror. I didn't really understand it all then, but it's been working fine. The problem is that now with I "make buildworld" and "make installkernel" I get the old original kernel, not the new one. I suspect it's because I'm not installing the kernel in the boot partition that's actually being used, but am out of my depth here and need some advice. Here's how I created the gmirror and installed onto it back then, per my notes. I had 2x 1TB drives and wanted to use a gmirror for the boot and ZFS for the rest: Did a minimal install onto a 1GB ad4s1a. fdisk -BI ad6 bslabel ad4s1 > /tmp/label bsdlabel -RB ad6s1 /tmp/label gmirror label boot ad6s1a newfs /dev/mirror/boot mount /dev/mirror/boot /mnt find -x / | cpio -pmd /mnt rm -rf /mnt/var/* /mnt/usr/* /mnt/tmp/* reboot gmirror insert boot ad4s1a Rebooting I believe is now booting from the gmirror comprised of ad4s1a and ad6s1a: $ df -h / /boot Filesystem Size Used Avail Capacity Mounted on /dev/mirror/boot 989M 634M 276M 70% / /dev/mirror/boot 989M 634M 276M 70% / After "make installkernel" my /boot/GENERIC is still from 2008, when I did the original installation. My /boot/kernel is new, from the installkernel. What am I missing? It seems I am not "installkernel"-ing to the right place where the boot loader is looking. Thanks.
