When I have a non-bootable ZFS partition with a zpool in it, bhyve decides that is the root and fails to boot the UFS root fs. I need to: currdev=disk0s1 boot to get it to boot. I don't know if this is what you might be seeing? rick > > thanks, > danny > ps: i guess i forgot to mention that the host is running in bhyve (14.3) > pass: it’s now alpha-5 >help
