1 Installation ************** These are the step-by-step instructions for installing Carbs Linux. 1.1 Preparing Environment ========================= 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: * tar * wget * xz * 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. 1.1.1 Download -------------- 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 'x86_64' with '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 We can then check the integrity of the tarball and do a signature verification. Even thought these are optional, they are highly recommended. 1.1.2 Check the integrity of the tarball (Recommended) ------------------------------------------------------ All of the releases are saved in a single file named 'sha256sums.txt', but the latest release is saved on 'carbs-rootfs.tar.xz.sha256'. You can acquire and verify the tarball. $ wget $URL/carbs-rootfs.tar.xz.sha256 $ sha256sum -c carbs-rootfs.tar.xz.sha256 1.1.3 Verify the signature -------------------------- It is highly recommended to verify the signature of the tarball. You will need GPG for this. $ wget $URL/carbs-rootfs.tar.xz.sig $ gpg --recv-keys FF484BDFEFCEF8FF $ gpg --verify carbs-rootfs.tar.xz.sig 1.1.4 Extracting the tarball ---------------------------- You will need to extract the tarball to your desired location. For partitioning, you can follow this guide (https://wiki.archlinux.org/index.php/Partitioning). This will assume that you will be mounting your root partition to '/mnt'. $ mount /dev/sdx1 /mnt $ tar xf carbs-rootfs.tar.xz -C /mnt 1.1.5 Obtain the chroot helper ------------------------------ You can obtain the 'cpt-chroot' script in order to do a simple chroot into your new root filesystem. $ wget https://dl.carbslinux.org/distfiles/cpt-chroot $ chmod a+x cpt-chroot 1.2 Chroot ========== Chroot into Carbs Linux! $ ./cpt-chroot /mnt 1.2.1 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 'git' or '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 'git' itself. The following guide will assume that you put the repositories into '~/repos/' directory, but you can put the repositories into any directory you want. So go ahead and create that directory. 'mkdir -p $HOME/repos'. 1.2.1.1 Obtaining from rsync ............................ Carbs Linux rsync repositories live in . In order to obtain it, run the following: $ rsync -avc rsync://carbslinux.org/repo $HOME/repos/carbs 1.2.1.2 Obtaining from git .......................... Carbs Linux git repositories can be found both from the main server and GitHub (mirror). Here are both their repository links. You can clone any of them. * * $ git clone git://git.carbslinux.org/repository $HOME/repos/carbs 1.2.1.3 Making the package manager use the repositories ....................................................... In your shell's configuration file, or in your '~/.profile' file, add the following lines: export CPT_PATH='' CPT_PATH=$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 1.2.2 Updating packages ----------------------- 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 1.2.3 Installing packages ------------------------- 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 1.2.4 Essential Software ------------------------ Here is a list of software that you might want to have on your system. BOOTLOADERS * efibootmgr * grub FILESYSTEMS * e2fsprogs * dosfstools * ntfs-3g NETWORKING * dhcpcd * wpa_supplicant TEXT EDITORS * nano * vim * neatvi * nvi * emacs * emacs-nox (terminal-only version of emacs) USER SHELLS * bash * zsh * dash * oksh * rc POSIX BASE UTILITIES * busybox * sbase * coreutils DOCUMENTATION * carbs-docs * man-pages * man-pages-posix 1.2.5 Obtaining the documentation (optional) -------------------------------------------- All the documentation for Carbs Linux can be found on a single info manual to be viewed offline. You can obtain texinfo or the info (standalone) package 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 1.3 System Configuration ======================== After you have finished installing some extra packages, you can configure your system to your liking. 1.3.1 Configuring hostname (recommended) ---------------------------------------- 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 1.3.2 Setting up hosts file (optional) -------------------------------------- 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 1.4 Kernel ========== Kernel isn't managed under the main repositories, even though you could package one for your personal use. Here is an example kernel package (https://github.com/cemkeylan/kiss-repository/tree/master/personal/linux), which you will need to reconfigure for your specific setup if you want to make use of it. 1.4.1 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-5.7.6.tar.xz $ tar xf linux-5.7.6.tar.xz Change directory into the kernel sources $ cd linux-5.7.6 1.4.2 Installing dependencies ----------------------------- In order to compile the kernel you will need to install some dependencies. You will need 'libelf' to compile the kernel. If you want to configure using the menu interface you will also need 'ncurses'. 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 (https://github.com/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 1.4.3 Compiling the kernel -------------------------- Next step is configuring and building the kernel. You can check Gentoo's kernel configuration guide (https://wiki.gentoo.org/wiki/Kernel/Configuration) 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 1.5 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. 1.5.1 Installing a bootloader ----------------------------- 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 1.5.2 Installing init scripts ----------------------------- 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 1.5.3 Generating fstab ---------------------- 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 1.6 Post-installation ===================== The base installation is now complete, you can now fine tune your system according to your needs. Rest of these instructions are completely optional. 1.6.1 Acquiring kiss repositories --------------------------------- While not 100% compatible with cpt, you can use kiss repositories in your system the same way you are using the distribution repositories. Here is an example for the KISS Linux Community repository. $ git clone https://github.com/kisslinux/community $HOME/repos/kiss-community $ export CPT_PATH=$CPT_PATH:$HOME/repos/kiss-community/community NOTE: There are lots of packages on the KISS community repository that are also on Carbs Linux main repository. I would advise giving lower priority to the KISS community repository as it may affect other packages that you might install.
