此处跟踪了 Bedrock Linux 的脚本和配置文件（默认值）等内容的开发进度
Bedrock Linux is a Linux distribution composed of user-selected components from various other Linux distributions. For example, with Bedrock one may use the installation process from one distribution, the init from another, a window manager from a third, and a web browser from a fourth. Bedrock strives to make these components work together as transparently as possible such that for day-to-day operations it is not readily evident that the various components were originally intended for disparate distributions.
This repository contains all the userland code for a Bedrock Linux system. It can create a script which may be used to install or update a Bedrock Linux system.
On a Linux system, install the build dependencies:
Ensure you have internet access (to fetch upstream dependencies), then run:
make GPGID=
to build a signed install/update script or
make SKIPSIGN=true
to build an unsigned install/update script.
The build process can be customized in the same fashion as most make and C projects:
-jN to tell make to parallelize the build process with N
jobs.CFLAGS to pass flags to the C compiler such as -Os and
-march=native.-static in various places. Do not set -dynamic or otherwise
try to change away from a static build.This will produce a script such as:
bedrock-linux-0.7-x86_64.sh
which may be used to install or update a Bedrock Linux system.
Installation
bedrock-linux--.sh script onto the system, either by
building it locally or getting a pre-built version from elsewhere.--hijack flag.brl fetch --list to see the various distributions which Bedrock knows
how to fetch.brl fetch to acquire upstream distribution files.--release and --mirror flags.A Bedrock Linux system is composed of "strata". These are collections of interrelated files. These are often, but not always, one-to-one with other, traditional Linux distributions. Bedrock integrates these strata together, creating a single, largely cohesive system with desirable features from other distributions.
To list the currently installed (and enabled) strata, run:
$ brl list
To list distros which can be easily acquired as strata, run:
$ brl fetch --list
To acquire new strata, run (as root):
# brl fetch
Once that has completed, you may run commands from the new strata. For example, the following series of commands make sense on a Bedrock system:
$ sudo brl fetch arch debian
$ sudo pacman -S mupdf && sudo apt install texlive
$ man pdflatex
$ pdflatex preexisting-file.tex && mupdf preexisting-file.pdf
Bedrock's integration is not limited to the command line. For example, graphical application menus or launchers will automatically pick up applications across strata, and Xorg fonts installed from one stratum will be picked up in an X11 graphical application from another stratum.
If there are multiple instances of an executable, Bedrock will select one by
default in a given context. If there are hints it can pick up on for which one
to use, it is normally correct. brl which can be used to query which Bedrock
will select in a given context. For example:
$ # arch, debian, and centos are installed.
$ # running debian's init, and thus must use debian's reboot
$ sudo brl which -b reboot
debian
$ # only arch provides pacman, so arch's pacman will be used
$ brl which -b pacman
arch
$ # yum is a python script. Since yum comes from centos, the python
$ # interpreter used to run yum will also come from centos.
$ sudo yum update
^Z
$ brl which $(pidof python | cut -d' ' -f1)
centos
If you would like a specific instance, you may select it with strat:
$ # arch, debian, and ubuntu are installed
$ # install vlc from arch
$ sudo pacman -S vlc
$ # install vlc from debian
$ sudo strat debian apt install vlc
$ # install vlc from ubuntu
$ sudo strat ubuntu apt install vlc
$ # run default vlc
$ vlc /path/to/video
$ # run arch's vlc
$ strat arch vlc /path/to/video
$ # run debian's vlc
$ strat debian vlc /path/to/video
$ # run ubuntu's vlc
$ strat ubuntu vlc /path/to/video
To avoid conflicts, processes from one stratum may see its own stratum's
instance of a given file. For example, Debian's apt and Ubuntu's apt must
both see their own instance of /etc/apt/sources.list. Other files must be
shared across strata to ensure they work together, and thus all strata see the
same file. For example, /home. Such shared files are referred to as
"global". Which stratum provides a file in a given context can be queried by
brl which:
$ # which stratum is my shell from?
$ brl which --pid $$
gentoo
$ # that query is common enough the PID may be dropped
$ brl which
gentoo
$ # which stratum provides ~/.vimrc
$ brl which --filepath ~/.vimrc
global
$ # global indicates all stratum seem the same file; not specific to any
$ # stratum.
$ brl which --filepath /bin/bash
gentoo
$ brl which --bin pacman
arch
If you would like to specify which non-global file to read or write, prefix
/bedrock/strata// to its path.
$ brl which --filepath /bedrock/strata/debian/etc/apt/sources.list
debian
$ brl which --filepath /bedrock/strata/ubuntu/etc/apt/sources.list
ubuntu
$ # edit debian's sources.list with ubuntu's vi
$ strat ubuntu vi /bedrock/strata/debian/etc/apt/sources.list
brl provides much more functionality which can be read from brl --help.

To sanity check your work (e.g. before upstream changes to Bedrock Linux), install:
Run
make format
to standardize the formatting of any changes you may have made, then run
make check
to run various sanity checks against the code base.
