But being able to run Linux in 4Meg or even 8M is important to a very large class of applications. Even if you are concerned mostly about bigger systems, making sure NT remains at a serious disadvantage in the embedded boxes is key because MS will certainly hope to use control of SOHO routers, set-top boxes etc to set "standards" that will improve their competitivity in desktop and beyond. It would be a delicious irony if MS were able to re-use against Linux the "first control low end" strategy that allowed them vaporize the old line UNIXes, but irony is not as satisfying as winning. - 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/
