It gets the command line argument passed to ifconfig after "eth0" from
the value of an environment variable —variable ETH0_IP in this case—,
instead of hardcoding it in the script like in your first example. The
shell equivalent of that would be:
ifconfig eth $ETH0_IP etc..
In turn, one can set values of environment variables from a text file
using execline's envfile program, or from an environment directory
using s6's s6-envdir program.
