Solved use identified device for zroot?

[benoitc]

When installing a new system Freebsd create a zroot with physical devices name:

 zpool status
  pool: zroot
 state: ONLINE
config:

    NAME        STATE     READ WRITE CKSUM
    zroot       ONLINE       0     0     0
      mirror-0  ONLINE       0     0     0
        da8p3   ONLINE       0     0     0
        da9p3   ONLINE       0     0     0

how to use instead the gpt label inside so it can be move lated and doesn't depend on the position in the backplane?

Boot a installation media, create a temporary mount point, import pool, using device GPT labels, reboot system.

 # zpool  import  -R  /tmp/a  -d  /dev/gpt  zroot

See zpool-import(8) '-d' option for details.

Note that once ZFS has it's hands on a disk the order really doesn't matter anymore. ZFS will find the proper disks (in the proper order) based on the meta data that's on it.
