Get the stage 3 installation file from https://www.gentoo.org/downloads/. I personnaly use the non-multilib one from the advanced choices, since I am no longer using and 32bits software except steam, and I use steam from a multilib chroot.
Put the archive on the server in /mnt/gentoo (you can simply wget it from there), then extract it :

## Initial configuration
We prepare the local language of the system :
-{{< highlight sh >}}
+```sh
echo 'LANG="en_US.utf8"' > /etc/env.d/02locale
echo 'en_US.UTF-8 UTF-8' >> /etc/locale.gen

echo 'nameserver 1.1.1.1' > /etc/resolv.conf

We set a loop device to hold the portage tree. It will be formatted with optimisation for the many small files that compose it :
-{{< highlight sh >}}
+```sh
mkdir -p /srv/gentoo-distfiles
truncate -s 10G /portage.img
mke2fs -b 1024 -i 2048 -m 0 -O "dir_index" -F /portage.img
tune2fs -c 0 -i 0 /portage.img
mkdir /usr/portage
mount -o loop,noatime,nodev /portage.img /usr/portage/
-{{< /highlight >}}
+```
We set default compilation options and flags. If you are not me and cannot rsync this location, you can browse it from https://packages.adyxax.org/x86-64/etc/portage/ :
-{{< highlight sh >}}
+```sh
rsync -a --delete packages.adyxax.org:/srv/gentoo-builder/x86-64/etc/portage/ /etc/portage/

## Introduction
Now that I am mostly running OpenBSD servers I just use genkernel to build my custom configuration on each node with :
-{{< highlight sh >}}
+```sh
eselect kernel list
eselect kernel set 1
genkernel all --kernel-config=/proc/config.gz --menuconfig
nvim --diff /proc/config.gz /usr/src/linux/.config

Bellow you will find how I did things previously when centralising the build of all kernels on a collab-jde machine, and distributing them all afterwards. Local nodes would only rebuild local modules and get on with their lives.

## Introduction
Here is my go to set of commands when I upgrade a gentoo box :
-{{< highlight sh >}}
+```sh
emerge-webrsync
eselect news read
-{{< /highlight >}}
+```
The news have to be reviewed carefully and if I cannot act on it immediately I copy paste the relevant bits to my todolist.
## The upgrade process
I run the upgrade process in steps, the first one asking you to validate the upgrade path. You will also be prompted to validate before cleaning :
-{{< highlight sh >}}
+```sh
emerge -qAavutDN world --verbose-conflicts --keep-going --with-bdeps=y && emerge --depclean -a && revdep-rebuild -i -- -q --keep-going; eclean --deep distfiles && eclean --deep packages && date
-{{< /highlight >}}
+```
After all this completes it is time to evaluate configuration changes :
-{{< highlight sh >}}
+```sh
etc-update
-{{< /highlight >}}
+```
If a new kernel has been emerged, have a look at [the specific process for that]({{< ref "kernel_upgrades" >}}).
