The smallest I've gotten a rootfs + kernel + ramdisk for minimal Debian, is 49MB, or 23MB with a localyesconfig kernel. And that was using squashfs, so you'd need more RAM to actually run it.
http://etbe.coker.com.au/2008/05/22/xen-and-swap/ In 2008 I found that a default Debian initrd produced on a system with LVM needed 30M of RAM to boot. Getting a virtual machine to boot with 13M of RAM took as much effort as I was prepared to invest in that project. It seems most likely that memory use has only increased since then. http://etbe.coker.com.au/2008/08/28/swapping-to-a-floppy-disk/ Sometimes I miss the good old days when 8M of RAM and a floppy disk as a swap device would do. In the really old days I had Linux running well in 4M of RAM. On Fri, 12 Jul 2013, Andrew McGlashan <andrew.mcglashan@affinityvision.com.au> wrote:
P4 is overkill and a power hog compared to many newer processors, ATOM, cough ... ARM or AMD, there are plenty of low power units now that are very cheap and not limited too much (especially by RAM).
http://doc.coker.com.au/environment/computer-power-use/ If you are after a 100baseT router than a P3 is the best option. A P3 uses a lot less power than a P4 and most machines of that era had plenty of PCI slots. PCI Ethernet boards are also easy to get. For file servers nowadays you need SATA for capacity which means that you need at least one of the later Celerons. Also some of the 64bit processors such as the E2160 use less power than P4 CPUs, only a couple of Watts more than a high-end Celeron. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
