NFS-RAMBOOT - How-To for Debian 9 Stretch

Posted 06-30-2017 at 06:09 PM by IsaacKuo

NFS-RAMBOOT adapts my RAMBOOT hack to NFS root (PXE or not). On boot, it extracts an OS tarball from an nfs share into local RAM (recommended 3+GB of RAM). The result is like a very fast SSD.

Why do this? Compared to RAMBOOT, loading (and saving) the OS tarball over gigabit ethernet can be faster than a local hard drive or USB drive, if the file server has an SSD or a faster hard drive (compare 3.5" drives to 2.5" laptop drives, for example). Also, having the OS tarballs...

tmpfs nfs swapfile - use one computer's RAM as SWAP for another computer

Previously, I described how to use one computer's RAM as an SSD (OS drive) for another computer. Here, I describe how to use one computer's RAM as SWAP for another computer. Bear in mind that even a RAM disk over gigabit ethernet isn't going to be as fast as a local SSD, but it's still faster and much more responsive than a local spinning hard drive.

This technique of using another computer's RAM as SWAP is a great way to augment RAMboot, as described here:

I have refined and updated my RAMboot how-to for Debian 8. Honestly, my previous how-to's still work fine for Debian 8, regardless of the switch to systemd. I have, however, tightened things up.

The basic concept is to boot from a local hard drive or USB drive, using a modified initrd to unpack ramboot/image.tar.gz to a tmpfs ramdisk. From then on, the system runs entirely from ram - uncompressed. This is like running off an extremely fast SSD, but with some important differences:...
