Reboot for pristine state?

Is there a distro or strategy/approach for returning an OS to a pristine state on every reboot? (almost like TailsOS, but more configurable/functional)


You’re looking for a stateles system, check out


I think, openSUSE MicroOS and Fedora SilverBlue would also fit your description.

And just in case it’s too obvious, most Live ISOs also work that way. So, the media that you normally use to install a distro, you can also just use without starting the distro installer. Some of them do persist changes to the USB stick or whatever you’ve burned them to, but most don’t.


+1 for MicroOS

I run it on my pi 3 and get rolling autoupdates+reboots that happen overnight. I never have to worry about having an out-of-date server. It can be adjusted if anyone is worried about downtime. It’s basically like having an automatic Arch Linux but in the openSUSE ecosystem. However directories like /var are preserved so that might not be what you’re looking for.


There is nixOS ( and guix ( which both use that approach

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
