List of Linux distributions that run from RAM

From Wikipedia, the free encyclopedia

Tiny Core Linux is an example of a Linux distribution that runs from RAM

This is a list ofLinux distributions that can be run entirely from a computer'sRAM, meaning that once theOS has been loaded to the RAM, themedia it was loaded from can be completely removed, and the distribution will run thePC through the RAM only. This ability allows them to be very fast, since reading and writing data from/to RAM is much faster than on ahard disk drive orsolid-state drive. Many of these operating systems will load from aremovable media such as aLive CD or aLive USB stick. A "frugal" install can also often be completed, allowing loading from a hard disk drive instead.

This feature is implemented in live-initramfs and allows the user to run a live distro that does not run from ram by default by addingtoram to the kernel boot parameters.[1]

Additionally some distributions can be configured to run from RAM, such asUbuntu using thetoram option included in theCasper scripts.[2]
