Are there any good Raspberry Pi distributions that load completely into RAM?

I know a few Linux x86 distributions that do this pretty well, but I want to do the same with my Raspberry Pi.

I would like to be able to boot from the SD card and then be able to remove it without errors.

  • You might want to look at this first: raspberrypi.org/phpBB3/viewtopic.php?t=48662&p=380872 There might be a module you could rmmod to stop that but OTOH: the source seems to be a hardware interrupt, indicating the pi responds to badly to the missing SD card. – goldilocks Sep 14 '13 at 12:18
  • I don't know if you know about the Linux distro "Puppy Linux", but the desktop edition runs completely on RAM. They've made a Raspi version called Puppi, but I'm not sure if that version runs completely on RAM – zeldarulez Sep 14 '13 at 20:37

Yes there is; my project Nard SDK
http://www.arbetsmyra.dyndns.org/nard/
does exactly what you want. It's a slimmed OS which runs entirely from RAM and has full support for removing the SD card in runtime.

You might also want to check out this operating system called slack linux. I did not try this with the pi but with a computer with 1 GB of ram. Therefore I beleive it would work on the Pi 2 because of the amount of ram. Here is a site for putting it on the Pi2.
