"Interestingly, the CD's Credits file mentions Ralph Yarro, among others. The copyright information states that they used Red Hat's Linux and then added some tweaks of their own to it, and they list files and applications that were not under the GPL, and none of the files in the screenshots are listed as excluded. All the rest, they say, were distributed under the GPL.

I asked Dr Stupid to look at the screenshots and tell me what it means to him, and here's what he told me:
"Well, it's confirmatory evidence that Caldera shipped errno and STREAMS under the GPL, in particular that they took the conscious decision to include STREAMS (since Red Hat didn't.)"
