The two organizations you name, and more besides do work on the Linux kernel. A lot. I realize that you're not deeply connected in the Linux community, so you may not realize much of this, but the simple fact is that RedHat and others do exactly what you say they don't. Caldera has contributed significantly to both the PPP code and IPX code in the Linux kernel. They've developed a SYSV Streams emulation (that Linus doesn't want in the main kernel :-), and some other stuff. RedHat employs Doug Ledford who works on (and has put a *lot* or work into) the Adaptec 7XXX driver. They employ Dave Miller who works on both multi-arch issues and oversees (and codes a fair portion) of the TCP networking. They (through his consulting firm) employ Alan Cox, who is often regarded as Linus' right-hand man, and was responsible for seeing the 2.0.36 and 2.0.37 stable kernels to release, plus whatever other scut jobs are out there. I believe RH also employs Stephen C. Tweedie, who does major work on the ext2 fs, including adding journaling. In fact, one could argue that if the people RedHat pays to work on the kernel disappeared, work on the kernel would suddenly get an awful lot slower. SUSE employs Andrea Arcangeli, who is doing a ton of work on the Linux VM system. SUSE has also developed X servers which they then contrib'd back to XFree86.org, which arguably benefits even more people since XF86 works on the *BSDs (including BSD/OS, no?) (and which, since XF86 is under the MIT license, someone could then take and make proprietary...fair?). So, in light of these new facts, would you like to reassess your assessment? Mike.
