Linux entirely running from RAMDISK


hi there, i posted a while ago inquiring about which distro does the things i want it to.

let me start by saying i know very very very little about linux so forgive me if the terminology is wrong or the answer is obvious.

here is what i'm looking for: (so far the closest thing i've come across is puppy linux--whose focus is on small distro size however)

1) 64-bit kernel designed to run on recent hardware w/ at least 4 GB of RAM

2) runs entirely from RAMDISK... (loads from a source like CD/DVD/USB/tFTP then unmounts that source and works independently) -- so loads the whole contents of the source into RAM so the source does NOT need to be read in order to load applications.

3) designed from the ground up to be optimized for using RAMDISK (so it doesn't do any virtual swapping to RAM-- i guess i can just change the size of the swap file to 0)

4) compiled w/ drivers for ATi, Nvidia, Intel graphics chipsets and most hardware commonly found in current computers.

5) custom power states to be energy efficient while still keeping the ram refreshed so it doesn't lose any information.

6) realtime updates to source (persistent) if mounted (optional)

if anything that comes close to this is in development or already out there please point me in the right direction. again, the closest thing i've found thus far is puppy linux.

thank you linux community.

Insert Linux can be run from RAM-disk. It's intended as a rescue system, so it just has standard utilities, partition editor, text editor, web browser, etc, but you could add other stuff.

Otherwise, you'd be looking at running any small distro inside an emulator like Qemu; see

With slax you can build your own "live cd" and then run it from ramdisk. I havent tested every single module but every module I have tested works.

The most advanced live cd with a " copy2RAM "
function at start is PCLinuxOS 2009, AFAIK.
