This is a weird way to build a string; why are you not using
snprintf()? Not to mention that interface names can contain several
characters that are special to the shell - in fact the only disallowed
characters are / and whitespace.
Also, the external script will not be useful to anything other than
hv_kvp_daemon, so it probably belongs somewhere under /usr/share.
