butter-hopper
-------------

butter-hopper is a collection of tools to help making switching between multiple distros easier
butter-hopper allows you to try out multiple distros on a single large BTRFS partition using BTRFS subvolumes.

Features:
^^^^^^^^^


* butter-hopper uses ``systemd-nspawn`` to ``ch-boot`` into your desired distro
* And if you wanna take it for an actual spin on your hardware you can do that too
* butter-hopper will extract boot entries in the OS and present them in GRUB/rEFInd menu.
* Installing and upgrading various common packages on many distros can be time consuming.\ :raw-html-m2r:`<br>`
butter-hopper uses ``nix`` as package management/cache which can be used from any distro
* Support installing tools like IDE, VSCode which don't need to be packaged to ``/common``
* PLANNED: Using qemu/KVM to boot GUI to another distro

Pre:requesties
^^^^^^^^^^^^^^


* Make sure all of distro use systemd and support btrfs which should be any recent distro
* For the boot to hardware you want to make sure you have a recent version of GRUB2 installed with\ :raw-html-m2r:`<br>`
support for btrfs.

butter hopper tools
^^^^^^^^^^^^^^^^^^^


* ``btrhop`` : The main command line interface to btrhop which allows managing snapshots, running, upgrading distros
* ``bootcrapper`` and ``flatduck`` : Command line tools to bootstrap a distro from rootfs or docker images.
* ``mntem`` : A tool to help manage multiple mount points of BTRFS subvolumes/ shared storage.
* ``nixy`` : Helper script to install ``nix`` and setup packages on common ``/nix/store``

Sharing:
^^^^^^^^

While using a default user of ``1000`` and allowing any user to change stuffs in ``/home`` works.\ :raw-html-m2r:`<br>`
``butter-hopper`` recommends using differnt user ids of your primary user and supports in the config.\ :raw-html-m2r:`<br>`
To take a sample config of ``butter-hopper.conf`` look at my dotfile in your preferred Git hosting.\ :raw-html-m2r:`<br>`

Tips:
^^^^^

Change your default subvol to "/staging" so you dont accidentally mount the real root\ :raw-html-m2r:`<br>`
To do that simply run ``btrhop populate-distros --staging``

Working
^^^^^^^

This is the layout pulled directly from my current install.
butter-hopper installs distros to ``/distros`` in your btrfs partition
