I read somewhere on the Oracle Technology Network (oracle.com/technetwork) that one can
actually get a copy of the solaris 11 kernel source, downloaded to one system, for perusal while
developing applications and kernel modules. The link did not provide details and I suspect that is
only available to companies who are OPN, oracle partner network. This link
but when I click on it, I get page not found (Error page 404).
was I hallucinatinating when I read about access to the Solaris 11 kernel source?
I fear you might have been reading out of date information from the OpenSolaris days. Only a small handful of partners have access to the Solaris 11 kernel source - it's not generally available at this time.
