-system lives on squashfs
-  -> overlayfs with tmpfs set up at boot
-  -> new system image generated and written back on shutdown
-    -> user-selectable ("Do you want to save changes to the system? This will take some time.")

-when backing up
-- do not cross file system boundaries
-- exclude /tmp, package cache, logs
-- possibly only save the changes in separate squashfs images

-Steps to install:

   - select kb layout
   - install base system
     -> select installation type (x86_32/x86_64/aarch64, glibc/musl)

-    -> configure overlayfs setup
-      -> startup script
-      -> shutdown squashfs updater
-        -> rc.shutdown?
     -> configure time zone
       -> selection dialog?
       -> symlink /etc/localtime
-    -> set up an initramfs to mount the squashfs/overlayfs at boot time
     -> prepare 2nd stage installation
-      -> auto login root and put script in .bashrc

-        -> better method?
     -> build squashfs
   - prompt user to reboot to finish installation
-  - second stage installation
