One of the principal whines about the OpenSolaris distro
from the existing Solaris community has been that it doesn't support SPARC. As we discussed in the roadmap presentation
last month, it's planned for future releases, and one of our interns has recently published his work this summer on porting the distro to SPARC. Chris did a really great job on this, and while it's a ways from being done enough to release, his blog entries about the work are a good read. Check 'em out!
