My Gentoo Linux System

Hey, this is my tested Step by Step complete gentoo linux desktop install.

key features:

luks on lvm allow for mounting other encrypted drives
systemd
systemd-boot as the bootloader
silent boot
optimized

Tested only on my hardware make adjustments to suit your needs.

Gentoo install guide
Acknowledgments

Boot Gentoo live cd

make sure that we boot on UEFI mode:

efivar -l

Setting up Hard Drive

Partitioning

if NVME disk /dev/nvme0n1 if SATA disk /dev/sda/

cfdisk /dev/sda

Create LVM

pvcreate /dev/sda2
vgcreate vg0 /dev/sda2
lvcreate -l 100%FREE -n troot vg0

Create LUKS

cryptsetup luksFormat --type luks2 --cipher aes-xts-plain64 --key-size 256 --hash sha256 /dev/vg0/cryptroot
cryptsetup open /dev/vg0/root root

Create filesystems

mkfs.fat -F32 /dev/sda1
mkfs.ext4 /dev/mapper/root

Mount the filesystems

mount /dev/mapper/root /mnt/gentoo
mkdir /mnt/gentoo/boot
mount /dev/sda1 /mnt/gentoo/boot

Installing the Gentoo base system

Change into our mounted directory:

cd /mnt/gentoo

Ensure the date and time are set correctly.

chronyd -q

Install the stage3 tarball

Choose systemd stage3 profile:

links https://www.gentoo.org/downloads/#other-arches

Unpack the tarball:

tar xpvf stage3-*.tar.xz --xattrs-include='*.*' --numeric-owner

Chrooting

Copy DNS info:

cp --dereference /etc/resolv.conf /mnt/gentoo/etc/

Chroot into the new environment:

arch-chroot /mnt/gentoo
source /etc/profile
export PS1="(chroot) $PS1"

package.use/systemd

sys-apps/systemd 		        cryptsetup boot

package.use/util-linux

sys-apps/util-linux 	        cryptsetup

TO DO:

emerge -av dev-vcs/git
cd /etc/portage/
rm -rf make.conf package.use package.env package.accept_keywords package.mask
mkdir /etc/porage/env
cd
git clone https://github.com/criptixo/gentoo-linux-desktop
cd gentoo-linux-desktop
mv gentoo-linux-desktop/portage/* /etc/portage/

Choosing systemd profile

update the snapshot with the latest version of the repository: emerge-webrsync

List the available profiles:

eselect profile list

[..]
[17]  default/linux/amd64/17.1/systemd (stable) *
[..]

eselect profile set 17 # or the number that you have on your list

Re-compile

emerge --ask --verbose --update --deep --newuse @world

Configuring the base system

In addition to Portage, some other options should be configured.

Timezone/locale/hostname

setup timezone

echo Africa/Algiers > /etc/timezone
emerge --config sys-libs/timezone-data
hwclock --systohc

setup locale

nano -w /etc/locale.gen 
locale-gen
eselect locale list
eselect locale set 4
env-update
source /etc/profile

setup hostname

hostnamectl hostname navi

firmware/microcode

firmware:

emerge --ask sys-kernel/linux-firmware

microcode:

Installing the kernel

Gentoo sources

emerge --ask sys-kernel/gentoo-sources

eselect kernel list

Available kernel symlink targets:
  [1]   linux-5.15.59-gentoo

eselect kernel set 1

genkernel

Install genkernel:
```
emerge --ask sys-kernel/genkernel
```
Genkernel needs the /boot entry in the /etc/fstab file. So go to the fstab section now and continue with point 2 when you're done.
Edit /etc/genkernel.conf:
```
nano -w /etc/genkernel.conf
```
Ensure that LVM and LUKS are set to yes; otherwise, the system will not boot. Leave the rest of the options as they are:
```
# Add LVM support
LVM="yes"

# Add LUKS support
LUKS="yes"
```
Once genkernel is configured, then run to generate the kernel binary:
```
genkernel --loglevel=5 all
```

Configuring the modules

If we need to auto-load a kernel module each time to system boots, we should specify it in /etc/conf.d/modules file. You can list your available modules with:

find /lib/modules/<kernel version>/ -type f -iname '*.o' -or -iname '*.ko' | less

LVM Configuration

emerge --ask sys-fs/lvm2

nano -w /etc/lvm/lvm.conf

volume_list = ["vg0"]

Creating Swap

Fstab

Before editing fstab we need to know which UUID are using our devices inside and outside lvm and luks volumes:

blkid /dev/mapper/vg0-root | awk '{print $2}' | sed 's/"//g'
UUID="576e229c-cf68-4010-8d85-ff8149158416"
blkid /dev/mapper/vg0-home | awk '{print $2}' | sed 's/"//g'
UUID="95fa5807-ea57-4cf5-b717-74f4aba190e2"

/dev/mapper/root		/		    ext4		rw		    0 1
/dev/sda1			    /boot		vfat		rw		    0 2
/swapfile			    none 		swap 		sw	        0 0

crypttab

Warning!!! As we don't have encrypted partitions other than root, which the systemd must mount before the whole system start, we don't need to set it up there, so our crypttab must be empty.

systemd-boot

emerge --ask sys-libs/efivar
efivar -l

bootctl --path=/boot install

Every time there's a new version of the systemd you should copy the new binaries to that System Partition by running:

bootctl --path=/boot update

Add one entry into bootloader with this options:

nano -w /boot/loader/entries/gentoo.conf

title gentoo
linux /vmlinuz-6.6.30-gentoo-x86_64
initrd /initramfs-6.6.30-gentoo-x86_64.img
options crypt_root=/dev/mapper/vg0-root root=/dev/mapper/root dolvm quiet loglevel=3 vt.global_cursor_default=0 mitigations=off

Edit bootloader config:

nano -w /boot/loader/loader.conf

timeout 0

Efibootmgr

emerge --ask sys-boot/efibootmgr

To list the current boot entries:

efibootmgr -v

BootCurrent: 0003
Timeout: 1 seconds
BootOrder: 0003
Boot0000* Linux Boot Manager  HD(1,GPT,3eb8effe-8e1d-4670-987c-9b49b5f605b2,0x800,0x1ff801)/File(\EFI\systemd\systemd-bootx64.efi)
Boot0001* gentoo  HD(1,GPT,02f231b8-8f9a-471c-b3a9-dc7edb1bd70e,0x800,0xee000)/File(\EFI\gentoo\grubx64.efi)
Boot0003* Gentoo Linux  PciRoot(0x0)/Pci(0x1f,0x2)/Sata(2,32768,0)/HD(1,GPT,73f682fe-e07b-4870-be82-d85077f8aaa2,0x800,0x100000)/File(\EFI\systemd\systemd-bootx64.efi)

I'm only Gentoo in my system so I don't really need anything but the Gentoo entry so I just delete everything with:

efibootmgr -b <entry_id> -B
