Everest Linux is a source based Linux distribution.
+
It is intended to function somewhat like an Arch/Gentoo hybrid
+
+
History of Everest
+
2021 - The idea of a system that combines the simplicity of binary packaging with the flexibility of source based packaging was born
+
Early 2022 - Early prototypes of Glacier were created. These versions came with no multi-repository support, caching, or logging of any kind
+
Mid 2022 - Glacier reaches a stable release point
+
+
Design Principles
+
Our design principles guide the development of Everest. You may notice we share some of these with Arch.
+
Simplicity - We provide packages with almost zero modifications from upstream, except when necessary.
+
Flexibility - Everest is designed with flexibility in mind. Any modification can be achieved if the user has enough knowledge
+
User Choice - Users are free to make any choice they see fit; this includes using proprietary software through the multiverse repository.
+
User Centrality - We believe that instead of trying to cater to as many users as possible, we should only target those with interest and knowledge in Linux.
This guide goes into detail on how to install Everest.
+
Prerequisites
+
There are 2 officially supported ways of installing Everest, systemd/glibc/GNU or sysv/musl/busybox. This guide covers the musl/busybox installation as it recieves the most support and is the intended way. For the GNU installation, it may be a good idea to read the Linux from Scratch wiki.
+
+
For highly customized installations (such as a custom init), it is recommended to know exactly what you're doing.
+
+
Everest may be installed through 2 methods:
+
- ISO: can be flashed to a usb and booted
+
- rootfs tarball (RECOMMENDED): unpacked to a directory (usually /mnt) and instaled through an existing distribution.
+
+
Note that no matter what option you choose, you will need the rootfs tarball.
+
+
If you wish to install Everest Hike instead of Everest Summit, you can run setup-everest.
+
+
First Steps
+
Create a disk partition for your root filesystem, a boot partition, and any other partitions you may want to make.
+
+
Create valid filesystems on the partitions (FAT32 for boot, and Ext4/Btrfs/XFS/ZFS on root).
+
# mkfs.vfat -F32 /dev/boot
+
# mkfs.ext4 /dev/root
+
+
Mount the newly created root partition to /mnt/everest.
+
# mkdir /mnt/everest
+
# mount /dev/root /mnt/everest
+
+
Create the "EV" variable, which will save some typing down the road.
+
# export EV=/mnt/everest
+
Ensure the variable was created correctly. It will be very important to check this multiple times during installation.
+
# echo $EV
+
+
Unpacking Tarball
+
To install Everest, you will need the rootfs tarball containing the necessary toolchain.
# tar xpvf everestlinux-summit-X.X.X-systemd.tar.xz --xattrs-include='*.*' --numeric-owner
+
Enter the chroot environment. This will allow you to install system packages.
+
# chroot "$EV" /usr/bin/env -i \
+
HOME=/root \
+
TERM="$TERM" \
+
PS1='[everest-chroot] \u:\w \$ ' \
+
PATH=/usr/bin:/usr/sbin \
+
/bin/bash --login
+
+
Installing System Packages
+
Now that we are inside the chroot environment, we can install packages to the system.
+
Before we start, creating /etc/make.conf is recommended. This is so you can specify extra makeflags, most notably, the -jX flag will allow make to utilize more than 1 core.
+
# /etc/make.conf
+
+
MAKEFLAGS=-jX
+
+
The following symbols will be used to describe packages
+
-(!) Vital system package, do not omit.
+
-(S) Source package
+
-(B) Binary package
+
-(L) Long installation time
+
+
(!) (B) Glacier
+
This package contains the Glacier package manager, which manages installed packages on the system. It uses wget and tar as its backens, both of which are included in the tarball.
+
To install Glacier: # rm -rf /tmp/glacier && cd /tmp && git clone https://github.com/everest-linux/glacier &&
+cd glacier/install && chmod +x INSTALL-GLACIER.sh && sudo ./INSTALL-GLACIER.sh || doas ./INSTALL-GLACIER.sh
+
+
Note that Glacier cannot manage itself, so you will need to update every month or so.
+
+
(S) Man-pages
+
This package contains 2,000+ manpages for the system.
+
To install man-pages:
+
# glacier -f
+
[ ? ] man-pages
+
+
(!) (B) Iana-Etc
+
This package contains vital networking protocols.
+
To install Iana-Etc:
+
# glacier -f
+
[ ? ] iana-etc
+
+
(!) (S) libgcc
+
This package contains libraries for GCC.
+
To install libgcc:
+
# glacier -f
+
[ ? ] libgcc
+
+
(!) (S) (L) musl
+
This package contains the musl standard C library.
+
To install musl:
+
# glacier -f
+
[ ? ] musl
+
+
(!) (S) busybox
+
This package contains common UNIX utilities in a single binary.
+
To install busybox:
+
# glacier -f
+
[ ? ] busybox
+
+
(!) (S) (L) vim
+
This package contains the Vim text editor.
+
To install vim:
+
# glacier -f
+
[ ? ] vim
+
+
(!) (S) (L) Linux
+
This package contains the Linux kernel
+
You will need to cache this package if you wish to build a custom kernel. Prebuilt kernels are available under the names 'linux', 'linux-zen', 'linux-lts', etc. For a custom configuration, the package is called 'linux-custom'.
+
To install a prebuilt kernel:
+
# glacier -f
+
[ ? ] linux-{zen,lts,hardened,rt}
+
To install and configure a custom kernel:
+
# glacier -c
+
[ ? ] linux-custom
+
Change directory into the Glacier cache and move the package to /tmp
+
# cd /var/cache/glacier && mv linux-custom.tar.gz /tmp
+
Unpack the package
+
# tar xvf linux-custom.tar.gz
+
Ensure the kernel's source tree is clean
+
# make mrproper
+
Make desired configurations to the kernel
+
# make menuconfig
+
If using systemd as the init system, 'The IPv6 protocol [CONFIG_IPV6] is highly recommended.
Warning: Some documentation for the kernel recommends symlinking /usr/src/linux to the kernel source tree, however this is specific to 2.6 series kernels and MUST NOT BE CREATED as it can cause conflics with Glacier.
+
Warning: The headers in /usr/include should ALWAYS be the ones against which your standard C library was compiled. They should NEVER be replaced by either the raw kernel headers or the sanitized headers of any other kernel.
+
Create /etc/modprobe.d/usb.conf, which will ensure USB modules are started in the correct order
Now we must configure the system so it will boot correctly
+
As a recommendation for easy access to the root account, installing sudo or doas is highly recommended, as it will remove the need to log in as root with su and will only require invoking sudo or doas.
+
In the case of sudo, the following line will need to be uncommented from /etc/sudoers
+
%wheel ALL=(ALL) ALL
+
In the case of doas, /etc/doas.conf will need to be created, containing the following:
+
permit :wheel
+
Create /etc/hostname and enter the desired hostname for the system
+
Create /etc/hosts and enter the following
+
127.0.0.1 localhost
+
::1 localhost
+
127.0.1.1 localdomain hostname
+
Install a bootloader capable of loading a Linux system (such as grub)
+
In the case of grub, install os-prober and efibootmgr (for UEFI systems), then install grub:
+
Warning: Highly customized configurations may cause the bootloader to break. It is recommended to edit /etc/make.conf before building this package.
Once the bootloader has been installed, power off the system.
+
+
The End
+
You should be greeted by a shell prompt on first boot.
+
If you need assistaince with your installation, we have both IRC channels, a Revolt server, and a Discord server.

Everest Linux
+
A highly flexible, general purpose operating system, built off of the Linux kernel.
+
Why Everest?
+
Simple: Everest strives to be simple by design, coming with no pre-installed bloatware.
+
Stable: Everest is designed to be as stable as possible. Adopting a unique approach to package management, update any package whenever you want, or not at all. Plus, major package dependencies are not resolved automatically, reducing the possibility of needing to downgrade a library.
+
Fast: Everest compiles packages so they can run as efficiently as possible. Simply define your desired makeflags and you're ready to go.
+
Lightweight: Everest uses busybox and sysvinit to provide an extremely lightweight system.
+
Flexible: Everest supports higly customized installations, to the point where some of them can't even be considered Everest anymore.
