The zpool rc.d script runs before mountcritlocal now, with the new OpenZFS import. However, powernv (powerpc64 native on IBM hardware) puts /boot on a separate filesystem, which doesn't get mounted until after that point. This causes the zpool script to fail if zfs is not built into the kernel. This appears to have been fine before because zfs(8) would automagically import the pool when starting up (after mountcritlocal, required by zfsbe), but zpools don't get automatically imported anymore. A hack to workaround this I did was to add a '/etc/rc.d/zpool start' into the two startup blocks in /etc/rc.d/zfs, but that's probably the wrong solution.
Is this still an issue after r365348 changed the order?
