Jails Documentation in FreeBSD handbook

[Martin Stiemerling]

Hi there,

I am just working through the documentation on how to install jails and 
figured out (at least for me :) that one step is missing in the handbook:

https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/jails-build.html

It's required to have the FreeBSD src installed after this "The jail(8) 
manual page explains the procedure for building a jail:".

However, the steps above do not install the FreeBSD src when doing this 
on  11.2-RELEASE-p3

This is missing:
tar -xf /mnt/usr/freebsd-dist/src.txz -C $DESTDIR

Thanks and kind regards,

   Martin
