QUIT WISHING AND WATCH SGI
Of the many companies claiming to support Linux, you should take a look at some of the contributions SGI is making.
People complain about NFSv3, well SGI has provided that support for Linux. Add advanced filesystems (promised, albeit, not yet available) like XFS - superb. Kernel debugger. IO enhancements. Memory size enhancements. OpenVault, GLX, STL, the list goes on.
IRIX is a superb *nix, with a ton of great features, many unknown due to their horrible PR and marketing... Just because Solaris has such a high level of corporate deployment does NOT make it the best OS on the market. If that were the case, we'd all be praising Windoze here. http://oss.sgi.com (http://oss.sgi.com) starts you off - take notice of this effort. SGI appears truly committed to this - and given SGI's future roadmap, we'll be benefiting from this for years to come.
Just think, a company with a vested interest in bringing their commercial *nix features to Linux - providing a threaded ip stack, HARD real-time scheduling, etc, etc, etc. Pretty cool for all of us.
