/etc/rc.conf is just /bin/sh code. All you need to do is set
the variables -- usually by assigning a static string, but you
can use whatever constructs you want. Well - within reason. Making
something as critical as the system boot process depend on a bunch of
other files or processes is not a good idea on the whole.
You can include multi-line whitespace in the variables by using single
Assuming that the init script that processes this data isn't phased
by the inclusion of a bit of whitespace.
Or you can generate the required numbers, assuming they are
jail_box_ip=$( jot -w "66.252.2.%d" -s "," 5 4 )
