Attempting to upgrade an 8.0-RELEASE to 8.1-RELEASE failed on a system running a bootable ZFS partition. The system boots to the loader prompt and complains there's no bootable kernel. Running 'lsmod' shows there are four ZFS disks present. Thanks in advance for clues on fixing this, and also on the right way to upgrade FreeBSD systems with bootable ZFS partitions. Steps to reproduce: 1. Build 8.0-RELEASE system following the freebsd.org wiki: http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/RAIDZ1 In this case the system uses raidz1 across four SATA drives. 2. Upgrade to 8.1-RELEASE using the 'FreeBSD Update' directions: http://www.freebsd.org/releases/8.1R/announce.html 3. After first reboot, system boots to the loader prompt. dn
