Gentoo installs everything from source (except new bin repo!). It uses the source code and the building instruction Ebuild. the gentoolkit contains helpful tools e.g.

# euse get mening of useflag
euse -i gpm
# enable flag
euse -E gpm
# disable flag
euse -D gpm

# switch of X11 suport for package
flaggie app-editors/vim -X

# show architecture compatibility and version info
eshowkw cups

# get more info about ebuild
equery

# unmask package for compilation
flaggie app-editors/vim +~amd64

eix is a tool to help with searching the ebuild repository.

install

install not from Gentoo live image but from another distro with GUI!

1. boot from any linux cd.
2. create fielsystem and partitions like in Archlinux install. Be sure if using GPT or MBR!!
3. mount disks to /mnt/gentoo
4. cd /mnt/gentoo/
5. wget https://distfiles.gentoo.org/releases/amd64/autobuilds/20231224T164659Z/stage3-amd64-desktop-openrc-20231224T164659Z.tar.xz get the stage 3 tar.xz
6. tar xpvf stage3-*.tar.xz --xattrs-include='*.*' --numeric-owner extract arcive
7. compile options nano /mnt/gentoo/etc/portage/make.conf
   • check COMMON_FLAGS="-march=native -O2 -pipe"
   • if not all cores change: MAKEOPTS="-j4 -l5"
   • add RUSTFLAGS="${RUSTFLAGS} -C target-cpu=native"

     • https://github.com/MentalOutlaw/deploygentoo/blob/master/gentoo/portage/make.conf
8. select portage mirrors add GENTOO_MIRRORS="https://ftp.snt.utwente.nl/pub/os/linux/gentoo/" in etc/portage/make.conf
9. Gentoo ebuild repository cp /mnt/gentoo/usr/share/portage/config/repos.conf /mnt/gentoo/etc/portage/repos.conf/gentoo.conf
10. copy DNS: cp --dereference /etc/resolv.conf /mnt/gentoo/etc/
11. mounting file systems:

mount --types proc /proc /mnt/gentoo/proc
mount --rbind /sys /mnt/gentoo/sys
mount --make-rslave /mnt/gentoo/sys
mount --rbind /dev /mnt/gentoo/dev
mount --make-rslave /mnt/gentoo/dev
mount --bind /run /mnt/gentoo/run
mount --make-slave /mnt/gentoo/run

chroot /mnt/gentoo /bin/bash
source /etc/profile
export PS1="(chroot) ${PS1}"

11. (optional, if low ram) create swap
12. install ebuild repository: emerge-webrsync
13. (optional) update rep: emerge --sync
14. (optional) Reading news items: 1)eselect news list eselect news read 1 | less
15. Choosing the right profile
    1. this selects the @World packages (emerge --info)
    2. eselect profile list and eselect profile set 27 or the one you want.
16. set additional USE items (optional)
    1. copy the USE variable to the make.conf emerge --info | grep ^USE
    2. to remove a item you need to add a - in front.

    1. Linux Firmware:
       • emerge --ask sys-kernel/linux-firmware
    2. bootloader:
       • add grub to useflags
       • emerge --ask sys-kernel/installkernel
       • maybe you need to run dispatch-conf
    3. initramfs
       • add dracut to useflags
       • emerge --ask sys-kernel/installkernel
    4. get binary kernal
       • emerge --ask sys-kernel/gentoo-kernel-bin
       • or kernal from source emerge --ask sys-kernel/gentoo-kernel
       • emerge --autounmask-write gentoo-kernel-bin linux-firmware intel-microcode installkernel
