@dch "checksum=on" is fletcher4 for non-dedup datasets (there, it's sha256)
The microbenchmarks are determining the best implementation of the named checksum algorithm for your hardware. They don't influence the choice of checksum algorithm.
The checksum property only applies to new data blocks written to that dataset. Pool metadata is always fletcher4.

This sounds very much like the process was indeed worth it :)
Thanks, @Larvitz !
It's just like Christmas, but better! (none of that religious or commercial stuff)
From man zfsprops(7) on FreeBSD:
The default value is on, which automatically selects an appropriate algorithm (currently, fletcher4, but this may change in future releases).
So checksum=on means 'fletcher4' currently on FreeBSD.

It appears Linux root-on-ZFS is a mess. No standard way to do it. Kernel updates require recompiling ZFS. Boot environments are a cornucopia of constantly evolving hacks.
If you're actually using #ZFS on root, on #Debian, what's your preferred hack to make that happen? #sysadmin
I suspect #openzfsmastery might need to assume root on extFS and data on ZFS, leaving root-on-ZFS for the advanced user or a terminal chapter. :flan_disappointed:
I was just looking at Scala on Amiga and look how beautiful!

Unfortunately it does not support '!!' or '!$' ones ...
Want to cycle through multiple #screen windows automatically?
1. start screen session with > 1 windows
2a. on another terminal, run "while screen -X next; do sleep 30 ; done"
2b. alternatively, add crontab entry "screen -X next"
Of course, when you have multiple screen sessions, don't forget the session name
@mwl Heh... Was just documenting that for myself...
Mount /var/db/pkg/repos and /var/cache/pkg repo into the basejail
jailroot=/jails/poudriere
mount_nullfs /var/db/pkg/repos ${jailroot}/var/db/pkg/repos
mount_nullfs /var/cache/pkg ${jailroot}/var/cache/pkg
Update packages
pkg -r ${jailroot} upg -r FreeBSD-base
Clean up mounts
umount ${jailroot}/var/db/pkg/repos
umount ${jailroot}/var/cache/pkg
Today, I installed my first FreeBSD update after switching to pkgbase. It worked perfectly and felt much faster than the “old way” using `freebsd-update`. As a user, I also feel that I can better understand what is happening.
However, boot environments are no longer created automatically before updates to the base system.
