To install Carbs Linux, you will need a Live Linux ISO. For that purpose, you can obtain a Gentoo or Void Linux live image. You can follow their instructions to boot and setup your network.
You will need the following programs in order to install Carbs Linux:
- some form of base utilities (coreutils, sbase, busybox, etc.)
Rest of these instructions will assume that you have set all of these up, and will continue on that point.
First, we need to download the rootfs tarball. You can do the following in order
to obtain the rootfs. If you are using an i686 machine, replace the
i686. We are setting this in a URL variable so that we don't have to
write it every time.
URL=https://dl.carbslinux.org/releases/x86_64 wget $URL/carbs-rootfs.tar.xz.sha256 sha256sum -c carbs-rootfs.tar.xz.sha256
It is highly recommended to verify the signature of the tarball. You will need
the OpenBSD tool
signify(1) for this. Many distributions provide a package for
it, if you are using a Carbs Linux host, you can also install the package
otools which provides
signify. Download the signature first.
The signature file should say something similar to
untrusted comment: verify with carbslinux-2021.08.pub RWTK4GFDD7JiohUHBeJXuKw+/P3K4ZRR8jQud0iOxNDbn7WCFxQsxt9FUNSEiXfLjkm1Ez8c3esRG8oydrsFUFpBGtekFt5obgo=
Grab the key (which probably should be the latest one) that is written on the file from https://dl.carbslinux.org/keys/ so you can verify the signature. The latest Signify public key is also available on the package repository, so you can check the validity of the public key from multiple locations, or just copy paste that portion to a file and use that instead.
PUBKEY=carbslinux-2021.08.pub wget https://dl.carbslinux.org/keys/$PUBKEY
You can now verify the distribution tarball with signify.
signify -V -m carbs-rootfs.tar.xz -p $PUBKEY
If everything went alright, this should output:
Extracting the tarball
You will need to extract the tarball to your desired location. For partitioning,
you can follow this guide. This will assume that you will be mounting your root
mount /dev/sdx1 /mnt tar xf carbs-rootfs.tar.xz -C /mnt
Chroot into Carbs Linux by running the chroot helper inside the rootfs!
Setting up repositories
Newest tarballs do not come with repositories, so you will need to manually
obtain them, and set your
CPT_PATH environment variable. Carbs Linux
repositories can either be obtained by
rsync. While rsync
repositories are overall faster and smaller, git offers the whole history of the
repository and a means to manipulate your repository as you like it. If you want
to obtain the git repository, you will need to install
The following guide will assume that you put the repositories into
directory, but you can put the repositories into any directory you want. So go
ahead and create that directory:
mkdir -p $HOME/repos
Obtaining from git
Obtaining from rsync
Carbs Linux rsync repositories live in rsync://carbslinux.org/repo. In order to obtain it, run the following:
rsync -avc rsync://carbslinux.org/repo $HOME/repos/carbs
Making the package manager use the repositories
In your shell's configuration file, or in your
~/.profile file, add the
CPT_PATH=$HOME/repos/carbs/core CPT_PATH=$CPT_PATH:$HOME/repos/carbs/extra CPT_PATH=$CPT_PATH:$HOME/repos/carbs/xorg CPT_PATH=$CPT_PATH:$HOME/repos/carbs/community export CPT_PATH
It is good practice to make sure your system is up to date, especially before building new packages. If there is an update for the package manager you will need to update twice.
cpt-update && cpt-update
Since you are operating on a really small base, you might need to build and install new programs to extend the functionality of your system. In order to build and install packages new packages in Carbs, you need to execute the following. "Package" is not actually a package and is given as an example.
cpt-build package cpt-install package
Here is a small list of software that you might want to have on your system as you are setting up. You might want to check the Software section in the full documentation to learn more about other packaged software.
Obtaining the documentation
All the documentation for Carbs Linux can be found on a single info manual to be
viewed offline. You can obtain either
texinfo or the
info packages in order
to view the documentation.
# Install the documentation. cpt b carbs-docs && cpt i carbs-docs # Install either texinfo or the info package. We will be installing standalone info # as it doesn't need perl. cpt b info && cpt i info # You can then run info and navigate through the documentation. info carbslinux
After you have finished installing some extra packages, you can configure your system to your liking.
You might want to add a hostname, especially in a networked environment. Your hostname will default to 'carbslinux' unless you set this.
echo your-hostname > /etc/hostname
You can edit your /etc/hosts file, which is the static lookup table for host names. By default, there are two entries for localhost which are OKAY. You can replace the 'localhost' part of these entries to your hostname.
127.0.0.1 localhost.localdomain localhost ::1 localhost.localdomain localhost ip6-localhost
Kernel isn't managed under the main repositories, even though you could package one for your personal use. Here is an example kernel package, which you will need to reconfigure for your specific setup if you want to make use of it.
Obtaining the kernel sources
You can visit the https://kernel.org website to choose a kernel that you want to install. Though only the latest stable and longterm (LTS) versions are supported.
# Download the kernel and extract it wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.9.1.tar.xz tar xf linux-5.9.1.tar.xz # Change directory into the kernel sources cd linux-5.9.1
In order to compile the kernel you will need to install some dependencies. You
bison to compile the kernel. If you want to configure
using the menu interface you will also need
# The package manager asks to install if you are building more than one package, # so no need to run 'cpt i ...' cpt b libelf ncurses
In the vanilla kernel sources, you need perl to compile the kernel, but it can be easily patched out. You will need to apply the following patch. Patch was written by E5ten. You will need to obtain and apply the patch in the kernel source directory.
wget https://dl.carbslinux.org/distfiles/kernel-no-perl.patch patch -p1 < kernel-no-perl.patch
Building the kernel
Next step is configuring and building the kernel. You can check Gentoo's kernel configuration guide to learn more about the matter. Overall, Gentoo Wiki is a good place to learn about configuration according to your hardware. The following will assume a monolithic kernel.
make menuconfig make install -Dm755 $(make -s image_name) /boot/vmlinuz-linux
Making your system bootable
In order to be able to boot your fresh system, wou will need an init-daemon, init-scripts and a bootloader. The init daemon is already provided by busybox, but you can optionally change it.
In the main repository, there is efibootmgr and grub to serve as bootloaders. efibootmgr can be used as a standalone bootloader, or can be used to install grub in a UEFI environment. efibootmgr is needed unless you are using a device without UEFI support (or you really want to use BIOS for a reason).
GRUB BIOS installation
cpt b grub && cpt i grub grub-install --target=i386-pc /dev/sdX grub-mkconfig -o /boot/grub/grub.cfg
GRUB UEFI installation
cpt b efibootmgr && cpt i efibootmgr cpt b grub && cpt i grub grub-install --target=x86_64-efi \ --efi-directory=esp \ --bootloader-id=CarbsLinux grub-mkconfig -o /boot/grub/grub.cfg
Only thing left to do is installing the init-scripts, and now you are almost ready to boot your system!
cpt b carbs-init && cpt i carbs-init
You can now manually edit your fstab entry, or you can use the genfstab tool. If you want to use the tool, exit the chroot and run the following:
wget https://github.com/cemkeylan/genfstab/raw/master/genfstab chmod +x genfstab ./genfstab -U /mnt >> /mnt/etc/fstab
The base installation is now complete, you can now fine tune your system according to your needs. Rest of these instructions are completely optional. You can check the rest of the documentation to learn more about the system.
The IRC channel for Carbs Linux is located in
#carbslinux on libera.chat. You
can install the
catgirl package from the repository, or use a client of your
preference to join. Feel free to ask for help, or have a general chat.
There have been recent changes to the
kiss package manager that breaks
cpt. These changes throw away the entire premise of their
"static" packaging system.
cpt will never implement those changes, so don't
expect any KISS package that was changed during or after July 2021 to work with
