It would be great if we could document this. I too recently
ran into a mismatch. If you load the /etc/hostid so that the
code in jail0_init picks it up and sets the host uuid, then
/etc/rc.d/hostid, enabled by default, will come along and
see there's no smbios.system.uuid and generate a new
uuid and smack that bad-boy into the kern.hostuuid sysctl
unconditionally. It was easy enough for me to work
around this by setting smbios.system.uuid in the boot
env that I was booting from, though.

Nothing to do with the upgrade, just that we have
multiple mechanisms to specify this stuff, and the code
we use today is somewhat less than robust to cover all
the cases that should be supported, but wind up being
buggy.
