Wrong Ports-OSVERSION in jails

[Jochen Neumeister]

Hi all,

i installed a new FreeBSD 12.1 amd64.
As next, i Install a new Jail with "bsdinstall jail /jails/jail1-www" 
and update the jail with "freebsd-update -b /jails/jail1-www fetch install".

I mount the Ports-tree into the jail with a /etc/fstab.jail1-www:

    /usr/ports      /jails/jail1-www/usr/ports      nullfs  ro 0       0

Here the entry in jail.conf:

    jail1-www {
       host.hostname = "jail1-www.local";
       path = /jails/jail1-www;
       ip4.addr = "192.168.2.31";
       mount.fstab="/etc/fstab.jail1-www";
    }

When i connect into the jail, the Tree is available and ready to use 
with this entry in /etc/make.conf:

    KDIRPREFIX=/tmp
    DISTDIR=/tmp/distfiles
    PACKAGES=/tmp/packages

When i will, as example, install nginx:

    root at jail1-www:/usr/ports/www/nginx # make install clean
    make: "/usr/ports/Mk/bsd.port.mk" line 1204: UNAME_r
    (12.1-RELEASE-p3) and OSVERSION (1101001) do not agree on major
    version number.

    root at jail1-www:/usr/ports/www/nginx # uname -a

    returned non-zero status
    1101001

Here the output from the Mainsystem:

root at server-01:/etc # uname -a
FreeBSD server-01.home.xxxxxxxx 12.1-RELEASE-p3 FreeBSD 12.1-RELEASE-p3 
GENERIC  amd64
root at server-01:/etc # make -C /usr/ports/ -V OSVERSION
1201000

I delete the portstree and check i out again with svn, but the same....

Any tipps to fix this?
