Immutability#

This is a work in progress!

blendOS's immutability is layered, like any other immutable distro. Here's how it works:

(mermaid chart here)

  1. overlayfs is used to mount a read-only filesystem atop /usr/ and /var/lib/pacman
  2. A read-write filesystem is mounted atop /usr/local for custom system-wide configuration
  3. /etc/, the user's home folder and /usr/local remain writeable

Anything created outside of existing system folders (i.e. stuff not in /usr, /lib, /opt, etc) is writeable.

Built with Material for MkDocs.
