Hi All:
I'm just upgraded from FBSD 8.0 (amd64) to 8.1, I currently run with the ZFS 
file system containing root. I understand that in the past, after rebuilding 
world and kernel and upgrading the pool to version 14,  there have been some 
issues concerning bootcode not being able to read the upgraded pools. Does 
anyone know if this is still an issue?


Versions are:

zfs upgrade
This system is currently running ZFS filesystem version 3.

All filesystems are formatted with the current version.


zpool upgrade
This system is currently running ZFS pool version 14.

The following pools are out of date, and can be upgraded.  After being
upgraded, these pools will no longer be accessible by older software versions.

Use 'zpool upgrade -v' for a list of available versions and their associated
