Why such difference

[Hot2017]

sysctl kern.version
kern.version: FreeBSD 11.0-RELEASE-p2 #0: Mon Oct 24 06:55:27 UTC 2016
    root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC

and at the same time

freebsd-version
11.0-RELEASE-p8

 

[SirDice]

The last couple of updates didn't involve the kernel, so that still has the 'old' version number.

If you want to see both: freebsd-version -ku.
