Subject: Re: Scyld and GPL
Wow! I really stirred the pot, didn't I? Sorry, I might have not been
interpreted as intended. There was never any >>question that Scyld made the
binaries available for free. The question I intended to bring up was the
contrast between the perceived availability of the commercial versions vs.
the source code, as presented on the web site. With that cleared up, here
are some friendly rebuttals:

Making the image available is only what seems to be a best practice for most
of the major Linux distributions. If you look on the web sites (with the
intention of finding them as opposed to NOT finding them) they are
relatively easy to nail down without too much poking.

>Let me say that I am very impressed and satisfied with Scyld (which I PAID
for without complaint, and would do so again at any reasonable price.) My
only point is that the location of the code seems ambiguous when compared to
what is typically found on other distributions' websites. I know that more
than one potential linux cluster builder has been thwarted early on simply
due to not having the software readily available.
