"Linux could be about to fork. In a worrying parallel to the issue
that stopped Unix becoming a mass-market product in the 1980s -
leaving the field clear for Microsoft - a recent open source
conference saw a leading Linux kernel developer predict that there
could soon be two versions of the Linux kernel.
Each version of the kernel requires applications to be compiled
specifically for it. Today, only one Linux kernel is current but
Andrew Morton, lead maintainer of the Linux kernel for Open Source
Development Labs (OSDL), said that he expects the 2.7 version of the
platform to fork to accommodate large patch sets."
