Yes, and ISTR its being discussed on d-u perhaps 20 years ago.
It means that software can get the hostname resolved to an IP
address a) before DNS is running, and b) before any interfaces
are configured, or when they fail to get configured at all.
Otherwise, you get a response to ping, say, like:
  ping: connect: Network is unreachable
instead of a response from the loopback address.

The idea of the script is to make sharing it as trivial as using
scp directly. And if you use sneakernet to transfer the master
file and the script, the latter should still work, because Debian
sets up 127.0.1.1 at installation time.

Cheers,
David.
