 Through config file in `/usr/local/etc/reggae.conf` you can change values for
-anything Reggae is using. Ater `reggae network-init`, you'll get jail with DHCP
-and DNS which is used to lease IPs to jails and virtual machines and to
-register all resources in DNS so that you can use FQDN instead of IP addresses.
-The DNS jail IP is used in /etc/resolvconf.conf, so that changes of network
-parameters are passed to the appropriate jail. Also, host will use DNS jail IP
-in /etc/resolv.conf. In short, it enables you to not remember jail IPs when you
-have to use them, but use `<jail name>.<domain>` to reference them, in which
-case <domain> comes from /usr/local/etc/reggae.conf.
