They go for the "free" (as in free beer) distros and suffer > from missing drivers. a) the RHEL sources are freely available b) lots of people and organisations grab, tweak, and build them (including I might add many HPC sites using perfctr) c) there's at least one no-cost binary redistribution (CentOS) d) it's also easy to combine e.g. FC user-space with a self-compiled RHEL kernel, at least as long as they're closely matched (e.g. FC6 + RHEL5 is fine) (heck, I've even run FC6 on top of a SLES10.1 kernel) So everything's that's needed is out there. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
