Bedrock Linux 1.0beta2 Nyla Major Features

The typical explanation of Bedrock Linux:

A Bedrock Linux system is composed of software gathered from other, normally mutually exclusive, Linux distributions, which are made to interact as though they were all intended for the same distribution.

is a bit abstract, which often leads to misunderstandings. It may be best explained with examples. Below are some of the more noteworthy features of Bedrock Linux as of 1.0beta2 Nyla which best illustrate what Bedrock Linux does.

New to Nyla

Init system

Bedrock Linux can utilize any of a large number of init systems as provided by other distributions: if there is a distro out there that provides an init system you like, you're probably able to use it with Bedrock Linux. Openrc from Alpine or Gentoo, systemd from Centos or Debian or Arch, upstart from Ubuntu LTS (for now), runit from Void Linux, BSD-style from Slackware or Crux, etc.

After the bootloader prompt

Note this is Ubuntu's GRUB prompt - Ubuntu was hijacked for this example Bedrock Linux install

Bedrock Linux provides another menu to choose which init system to use for the given session.

Similar to most bootloader prompts, one can set a default and never see the menu, as well as configure things such as a timer before it automatically chooses the default. Once a choice is made, Bedrock Linux does some prep work then hands control of the session off to the specified init.

After that point the boot continues just as it normally would had that init been the one native to the system.

This is not multiboot - you're not picking which OS to boot into. Irrelevant of which init was chosen, it's booting into the same OS - same users, same packages installed, same configs, etc, as would be in place had any other init been chosen at the previous menu. Just a different init system is in use - one that happens to be from another distro.

Installation

Some people prefer a polished, user-friendly installation experience which abstracts away some of the gritty details underlying the installation process. These people may choose a distro such as Ubuntu or Linux Mint. Others prefer a more hands-on approach and would choose something like Gentoo, Arch, or LFS. Bedrock attempts to make all of these options available.

To install Bedrock Linux, one first installs another distro - Ubuntu, Mint, Debian, Gentoo, Arch, CentOS etc - then hijacks it, converting it into a Bedrock Linux system. Installation steps such as partitioning, setting up a bootloader, adding users, optionally setting up full disk encryption, etc, are all done via another distro's tools and process - almost any major distro, whichever the user would prefer.

This hijack installation process is new to the latest release and is, at the moment, a somewhat manual process. However, this release lays the groundwork for future Bedrock Linux releases in which we may eventually distribute binary packages. These could be portable shell scripts, or if users find it easier, they could be packaged natively to the about-to-be-hijacked distro and distributed through something such as Ubuntu PPA's or Arch AUR.

Eventually, one will be able to install a distro whose installation process/features is desirable, then trivially convert it into Bedrock Linux.

Preexisting Features

Executables

Bedrock Linux is able to utilize executables from other distributions such that they largely "just work" as though they were all from the same distribution. The executables can call each other, can all see the same general files, etc.

Three different package managers each install a different video player. All of these different video players can be launched from the same shell, see the same video, etc - all working as though they were from the same distro.

Man pages

A shell from one distro can call man from another which shows a man page from yet a third - all interoperating as though they were intended for the same distro.

Despite the fact that the shell is from Alpine Linux, the man executable is from Debian Jessie, and the man page is from Centos 7, all of these files "just work" together, largely indistinguishable from how they would have worked if they were intended for the same distro.

Application menus

Many user-friendly-oriented distros provide a graphical menu which lists/categorizes installed applications. These menus are populated automatically as new applications are added. Under Bedrock Linux, the menu items can be provided by different distros. They'll all automatically show up under the menu, just as they normally would if the application was native to the same distro that provided the menu. Clicking on the items launches them, just as it should.

Despite the fact that SMplayer, Kaffeine and VLC are all from different distros, they all show up and "just work" from the Application menu.

Icons

Typically, if a given distro is missing something such as icons in its repository, this is not a huge problem - one can usually go get them elsewhere and install them natively. However, if another distro does provide the desired icons, with Bedrock Linux, one can simply go get the icons from there, straight from that package manager.

Arch provides the flattr icon themes, Debian provides the MATE icon theme, both show up in LXDE's icon theme chooser.

Upcoming Features

To further cement the idea behind Bedrock Linux via examples, below are features which are being worked toward for future releases.

While just about everything from one distro "just works" with other things from that same distro, not everything "just works" works across distro boundaries. Such things can be installed redundantly via package managers across distros or, if they are unavailable in a given package manager / distro / repository, they can be compiled from source, grabbed a theme online, etc. Bedrock Linux development is working towards minimizing such scenarios. Various things being pursued:
