Re: [MirageOS-devel] Problems with Step 4 of Hello World

[Richard Mortier <mort@xxxxxxxxxx>]

I think updates need to be made to those docs, at least for stackv4.

It seems that when conduit came in, and HTTP was supported
differently, the "hello" part of that example was removed, leaving
only the console echo service. At present, if you type into the telnet
session, you should see output on the console of the mir-stackv4
process.

I've filed an issue to check the samples and update the docs. Will try
and get this fixed in the next few days if no-one beats me to it.
