What is Bedrock Linux?

From their website:

Bedrock Linux is a meta Linux distribution which allows users to utilize features from other, typically mutually exclusive distributions. Essentially, users can mix-and-match components as desired. For example, one could have:

• The bulk of the system from an old/stable distribution such as CentOS or Debian.
• Access to cutting-edge packages from Arch Linux.
• Access to Arch’s AUR.
• The ability to automate compiling packages with Gentoo’s portage
• Library compatibility with Ubuntu, such as for desktop-oriented proprietary software.
• Library compatibility with CentOS, such as for workstation/server oriented proprietary software.

All at the same time, all working together like one, largely cohesive operating system.

So, what is this thing? Bedrock Linux is a package manager compatibility overlay. Ever wanted to use CentOS or Arch packages on your Debian system? Bedrock Linux will let you do that.

Strata

A stratos in Bedrock Linux is a package management overlay. For example, if you want to add a CentOS Strata, you run:

$ sudo brl fetch centos

The BRL app will then download yum and it’s required apps and libraries into the overlay. Once it’s done you can then yum install whatever you want.

Have multiple versions of the same package? Use:

$ strat [stratus name] [packagename]

For example with the Nano editor:

tux@debian:~$ strat arch nano -V
GNU nano, version 4.2

There are problems

It’s not as easy as it sounds. In order to install Bedrock Linux, you must have a compatible base OS. Here is the list that’s currently on the website:

Distro	Hijack-able	Fetch-able	Maintainer
Alpine Linux	Yes	Yes	paradigm
Arch Linux	Yes	Yes	paradigm
CentOS	Known issues	Yes	paradigm
Clear Linux	Mixed reports	Experimental support	N/A
CRUX	Known issues	No	N/A
Debian	Yes	Yes	paradigm
Devuan	Needs investigation	Yes	paradigm
Elementary OS	Yes, but limited testing	No	N/A
Exherbo	Yes	In development	Wulf C. Krueger
Fedora	Yes	Yes	paradigm
Gentoo Linux	Yes	Yes	paradigm
GoboLinux	Known issues	No	N/A
GuixSD	Needs investigation	No	N/A
Manjaro	Yes, but pamac/octopi broken	No	N/A
Mint	Needs investigation	No	N/A
MX Linux	Known issues	No	N/A
NixOS	Known issues	No	N/A
OpenSUSE	Yes	Experimental support	N/A
OpenWRT	Needs investigation	Experimental support	N/A
Raspbian	Yes	Yes	paradigm
Slackware Linux	Known issues	Experimental support	N/A
Solus	Yes	Experimental support	N/A
Ubuntu	Yes	Yes	paradigm
Void Linux	Yes	Yes	paradigm

Hijack-able distros are suitable base installations. Fetch-able distros can be used as overlays.

However this isn’t entirely true or at least not up to date. My first attempt was with OpenSUSE Tumbleweed. After installing, it failed to boot. My second attempt was with Fedora 30. Same resume. It worked on the third try with vanilla Debian. Finally, while Fedora is listed as fetch-able, I couldn’t install it because the brl application couldn’t find a suitable mirror.

Should I give it a try?

Yes! It’s a very interesting project, but don’t do it on any machine where you need your data to be protected. A spare VM is the ideal platform until it becomes more stable.
