It will match if %s is anywhere in the string, it will strip it out and
it will no longer match the original path. Then we go into the code that
does the actual substitution.
The nice part about working in shell scripts is that it takes 3 seconds
to test out something you don't understand.

The kernel docs say IP address, but the actual kernel code uses the host
name if set and falls back to the IP address.
