RE: upgrading 13-stable on rpi4b/8GB

Hi list,

Is it reasonably safe to upgrade 13-stable/rpi4 at the moment?
The system runs zfs.

-- 
I use FreeBSD 14.0-CURRENT and just assume 13-stable/rpi4 is safe to upgrade.

Maybe make and test a booting USB Flash drive with your ZFS on root setup for the presently booting Raspberry Pi, so you have a method to boot and then repair after an upgrade.
  
IF you are running ZFS,  I would create a "snapshot" using bectl or beadm,  before upgrading, so you could get back to a booting configuration that you have now.

2nd  I would save a copy ALL the files and configurations in  the  ESP EFI FAT32 partition that is presently booting for you now.
3rd  I would save the /boot/kernel/kernel   file from on the mounted ZFS zpool for root directory '/'  I again would use a tool like md5deep or hashdeep to checksum the / and /boot directory files
4th  Make notes on the initial ZFS root directory,  zpool list,  zfs list zfs get all zroot


Here are some links that I share related to Raspberry Pi 4B.

    Thanks for the training you gave me with this ZFS material.  I 
benefited from your creative web post, to use creating a ZFS install to 
Raspberry Pi 4B USB SSD

      Audit your /boot files with md5deep audit tool

Make notes on file size, file date, and file md5sum or sha256sum 
checksums.  I use tool md5deep

What are your thoughts and success on using FreeBSD on root ZFS on a 
Raspberry Pi 4B, Void?  How much dram is on your Raspberry Pi 4B.
