My Gentoo Install

cfdisk, 512M Efi System, 2G Extended Boot, Rest of the space into Linux Filesystem
cryptsetup luksFormat on the root partition
cryptsetup open on the root partition
mkfs.vfat -F32 -n EFI on the EFI partition
mkfs.btrfs -L BOOT on the BOOT partition
mkfs.btrfs -L ROOTFS on /dev/mapper/root
Make btrfs subvols, @ @home @var @snapshots...
mount the root subvol with mount subvol=@,compress=zstd /dev/mapper/root /mnt/gentoo
mkdir for each of your subvols on /mnt/gentoo, for example: mkdir /mnt/gentoo/home
mount the other subvols with subvol=@NAMEOFSUBVOL,compress=zstd /dev/mapper/root /mnt/gentoo/NAMEOFFOLDER
cd /mnt/gentoo
download stage3 with links https://www.gentoo.org/downloads
install stage3 with tar xpvf stage3-*.tar.xz --xattrs-include='*.*' --numeric-owner -C /mnt/gentoo
Copy DNS info over to /mnt/gentoo with cp --dereference /etc/resolv.conf /mnt/gentoo/etc/
arch-chroot into /mnt/gentoo
mount efi partition to /efi
mount boot partition to /boot
emerge-webrsync
emerge --sync --quiet
eselect profile list (If unsure go with a desktop profile.)
eselect profile set [number] (Ensure it's the newest version of profile.)
add FEATURES to make.conf, set binpkg-request-signature, and if you want install to go faster set getbinpkg which makes portage prefer binaries, REMOVE GETBINPKG AFTER INSTALL (unless you want all binaries)
(optional because it can take a while) configure USE in make.conf
configure cpuid2cpuflags, emerge -1 cpuid2cpuflags, echo "*/* ${cpuid2cpuflags}" > /etc/portage/package.use/00cpu-flags
add VIDEO_CARDS to make.conf (if nvidia add "nvidia", if amd add "amdgpu radeonsi", if intel add "intel")
add ACCEPT_LICENSE="-* @FREE @BINARY-REDISTRIBUTABLE" to make.conf
add GRUB_PLATFORMS="efi-64" to make.conf
run getuto to setup portage keyring
emerge -av cryptsetup
(optional, will take a while) emerge -avuDN @world
(run if above was ran) emerge --ask --depclean
Setup timezone with ln -sf ../usr/share/zoneinfo/America/New_York /etc/localtime
nano /etc/locale.gen (uncomment locales to use)
locale-gen
eselect locale list
eselect locale set [number]
reload the environment with source /etc/profile
create /etc/portage/package.use/installkernel with grub and dracut use flags (sys-kernel/installkernel grub dracut)
mkdir /etc/dracut.conf.d
add this to /etc/dracut.conf.d/luks.conf, add_dracutmodules+=" crypt " and then on a newline kernel_cmdline+=" rd.luks.uuid=LUKSUUID " (the spacing inside the quotes is critical, it's how dracut works and is not a typo)
enable dist-kernel use flag in make.conf to regen kernel modules on kernel update
emerge installkernel and linux-firmware
make sure efi and boot partitions are mounted
grub-install --efi-directory=/efi
emerge gentoo-kernel-bin
emerge -av1 genfstab
genfstab -U / > /etc/fstab
echo YOURHOSTNAME > /etc/hostname
emerge dhcpcd
rc-update add dhcpcd default
run passwd to set root password
nano /etc/conf.d/hwclock and change to local for correct time in windows dual boot
time to emerge the system tools
emerge sysklogd (system logger)
(optional) emerge cronie (if you don't need cron then you should be fine, if unsure just emerge it)
(if cronie installed) rc-update add cronie default
(optional, faster file indexing) emerge mlocate
(optional but highly recommended, if you use a shell other than bash than this isn't needed) emerge bash-completion (for bash autocomplete when pressing tab)
emerge chrony (NTP for syncing system clock)
rc-update add chronyd default
(if UEFI) emerge dosfstools
emerge btrfs-progs
(if using NTFS drives) emerge ntfs3g
emerge io-scheduler-udev-rules (for correct scheduler behavior with nvme devices)
(if using Wi-Fi) emerge iw or wpa_supplicant

run "ip a" to grab your network device, ethernet starts with enp or eth
