Difference between 'uname -a' and 'freebsd-version' (inside jail)

[mwittemans]

All,

I'm trying to figure out the difference between the out put of 'uname -a' and 'freebsd-version', in a jail created in FreeNAS-11.1-U5 with the default jail template '.warden-template-standard-11.0-x64'.

root@tserver:~ # uname -a
FreeBSD tserver 11.1-STABLE FreeBSD 11.1-STABLE #0 r321665+e0c4ca60dfc(freenas/11.1-stable): Wed May 30 14:18:20 EDT 2018 root@nemesis.tn.ixsystems.com:/freenas-11-releng/freenas/_BE/objs/freenas-11-releng/freenas/_BE/os/sys/FreeNAS.amd64 amd64
root@tserver:~ # freebsd-version
11.0-RELEASE-p1

according to the template sure I must be running 11.0, but uname suggest differently.

Yes you are running 11.0 with a Warden based jail. Warden is being replaced with iocage going forward. Search the forum, there are literally hundreds of post about it.

uname is a system call, so it's probably just being passed to the kernel, which replies with its version, which is indeed 11.1 something.
