Hi,
I cannot find the recommended way to specify the devices to boot from on
13.4-STABLE FreeBSD 13.4-STABLE stable/13-n258224-f702110bc4bc. I am
using internal disks for the system and external for data:

The problem occurs when the disks from data array are assigned to
/dev/da0 and /dev/da1. The booting process starts and finishes on
remounting root RW, because it cannot find root file system. It depends
on the order of hardware initialization.
What is the recommended way of specifying internal disks in ZFS,
something like disks uid? The mount process tries to mount ZFS gpt/zfs0
and gpt/zfs1 (which are shown in zpool status), but they are not on
/dev/da0 and /dev/da1.
Thank you very much for your suggestions.
Regards,
lk
