I've not investigated further as I'm investigating something else.

It is a official pkgbase main boot kernel cotnext:

# uname -apKU
FreeBSD aarch64-main-pbase 16.0-CURRENT FreeBSD 16.0-CURRENT
main-n286569-1f68ca5802db GENERIC-NODEBUG arm64 aarch64 1600018 1600018

The system is a non-ZFS system (no zfs labels) but I did:

# zpool get all
you have mail
sysctl_register_oid: can't re-use a leaf (vfs.zfs.metaslab.condense_pct)!
ZFS filesystem version: 5
ZFS storage pool version: features support (5000)

to see what would happen, such as if zfs.ko would load. It did.
