Hello gentoomen, I am transitioning from Arch to Gentoo on my new rig and with the combination of systemd and LVM, and being my first time, I knew this would get confusing so I spent some time trying to plan it out.

Now I ask of you to peer review it and help me ascend on my glorious journey, if you see any errors/mistakes and any suggestions or recommendations are welcome. Thank you.
This is for: UEFI, Ethernet, LVM, and systemd.

Main hardware devices:

* Intel i7-6700k
* Nvidia GTX 980TI
* 16Gb DDR4 RAM
* ASUS X99‑A Motherboard
* Samsung 500Gb SSD
* Western Digital 2Tb HDD

Here is my game plan:

[Device Graph](

[Mount Graph](

*Slightly different from pics (eg. /boot/efi)

* SSH (or VNC)
* Decrease boot time
* Mail Server
* Gaming Rig
* Create snapshots to revert to when I fuck up
* WM ricing

Parts that I know are wrong and I need guidance for:

* Installing systemd instead of OpenRC.
* What to configure in the kernel

**Please note the comments I placed in different sections where I question what i've done.**

Setting time and date:

Downloading the stage tarball:

    # cd /mnt/gentoo

    # links

    // http, releases/amd64/autobuilds/current-stage3-amd64/

    // ‘D’ to download tarball, ‘Q’ to quit

Unpacking the stage tarball:

    # tar xvjpf stage3*.tar.bz2 --xattrs

Configure compile options:


    # nano -w /mnt/gentoo/etc/portage/make.conf

    // Any suggestions for options here would be great.

Mounting the necessary filesystems:

    # mount -t proc proc /mnt/gentoo/proc

    # mount --rbind /sys /mnt/gentoo/sys

    # mount --make-rslave /mnt/gentoo/sys

    # mount --rbind /dev /mnt/gentoo/dev

Entering the new environment:

    # chroot /mnt/gentoo /bin/bash

    # source /etc/profile

    # export PS1=”(chroot) $PS1”

Installing a portage snapshot:

    # emerge-webrsync

    # emerge --sync

Reading news items:

    # eselect news list

    # eselect news read

    # eselect news purge

Choosing the right profile:

    # eselect profile list

    # eselect profile set <insert # here>

    // At this point it tells me to look at the systemd page, but its not a continuation of this guide so it confuses me somewhat.


    # echo “America/Los_Angeles” > /etc/timezone

    # locale -a

    # eselect locale list

    # eselect locale set <insert # here>

    # env-update && source /etc/profile && export PS1=”(chroot) $PS1”

Installing the sources:

    # emerge --ask sys-kernel/gentoo-sources

    # ls -l /usr/src/linux

    // I decided against the hardened kernel as it causes too many problems with Steam.

I want to use rEFInd instead of Grub2

Grub2 is a boot manager and a bootloader.
rEFInd is a boot manager only.
running rEFInd to run grub2 is a feasible redundancy.
IMHO using rEFInd to select an efi stub kernel bootloader is preferable as a lower maintenance option.
Defund the FCC.

Follow the handbook until your own Gentoo will boot.
Now switch to systemd. Do check it still boots and that systemd is in use.

From there, the world is your oyster but adopt the approch of building on what you know works, so that when, not if, if breaks. you know what broke it.
Narrowing the problem field makes it much simpler to help you fix it.


Computer users fall into two groups:-
those that do backups
those that have never had a hard drive fail.
