The branch main has been updated by lwhsu:URL: https://cgit.FreeBSD.org/src/commit/?id=72a1cb05cd230ce0d12a7180ae65ddbba2e0cb6dcommit 72a1cb05cd230ce0d12a7180ae65ddbba2e0cb6d Author: Li-Wen Hsu <lw...@freebsd.org> AuthorDate: 2022-11-07 03:30:09 +0000 Commit: Li-Wen Hsu <lw...@freebsd.org> CommitDate: 2022-11-07 03:30:09 +0000 rc(8): Add a zpoolupgrade rc.d script If a zpool is created by makefs(8), its version is 5000, i.e., all feature flags are off. Introduce an rc script to run `zpool upgrade` over the assigned zpools on the first boot. This is useful to the ZFS based VM images built from release(7).

For someone who knows ZFS well, it is clear that only a zpool upgrade is done. Not so experienced people may assume there is a combination of zpool upgrade and zfs upgrade (more so for people which do not know what the difference is). Maybe you want to add some explicit documentation, that zfs upgrade + feature flags needs to be done by hand.
And this brings me to a second topic, we don't have an explicit list of features which are supported by the bootloader (I had a look at the zfs and the boot related man pages, if I overlooked a place, then the other places should reference this important part with some text).
