*/From:/* void <void_at_f-m.fm> */Date:/* Tue, 01 Aug 2023 14:19:42 UTC 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.

How much dram is on your Raspberry Pi 4B. Are you interested in the Newer RK3588 SoC single board computers like the Orange Pi 5 and the https://wiki.radxa.com/Rock5 with 8 cpus running FreeBSD?
