	~~== How to build the Alpine Linux kernel ==~~		''This draft was removed''

	This [[Tutorials and Howtos\|Howto]] quickly demonstrates how to build and compile the default Alpine Linux [[Kernels\|kernels]]. Kernel customizations (not covered here) allow you to experiment by adding/removing kernel modules/features. For example, Alpine releases multiple [[Kernels\|kernels]] (e.g. LTS, virt) that vary in features and file sizes. Alpine kernels extend the standard [https://www.kernel.org/linux.html Linux kernel] and build within a few minutes to a few hours (depending on the speed of your system) using <code>[[abuild]]</code>, [https://gitlab.alpinelinux.org/alpine/aports aports], and [https://pkgs.alpinelinux.org/package/edge/main/x86_64/alpine-sdk alpine-sdk].

	~~== Before you start ==~~
	A running instance of Alpine Linux and a non-root user with [https://pkgs.alpinelinux.org/package/edge/main/x86_64/doas doas] privileges (i.e. sudo, wheel group) are required to use <code>[[abuild]]</code>.

	~~== Build & install the kernel ==~~

	~~=== Build ===~~
	~~<pre>~~
	~~doas apk add alpine-sdk~~
	~~doas addgroup USERNAME abuild # your non-root user~~

	~~git clone --depth 1 https://gitlab.alpinelinux.org/alpine/aports.git~~
	~~abuild-keygen --append --install~~
	~~doas chmod a+r /etc/apk/keys/* # ensure new keys are readable~~

	~~cd aports/main/linux-lts/~~
	~~time abuild -crK~~
	~~</pre>~~

	~~=== Identify backup ===~~

	~~Identify the package name of your current kernel (e.g. linux-lts, linux-virt). This example shows that~~ '''~~linux-lts~~'~~'' is the current package that we would revert to as a backup.~~

	~~<pre>~~
	~~echo "kernel: $(uname -r)"~~
	apk list --installed linux-*
	~~</pre>~~

	~~[[File:Alpine-kernel-package2.png\|600px]]~~

	~~=== Install ===~~
	~~Find the newly-built kernel file to install. This example shows how to install a newly-built x86_64 LTS kernel:~~

	~~<pre>~~
	ls -r ~/packages/main/*
	~~doas apk add FILENAME~~
	~~doas reboot~~
	~~</pre>~~

	~~[[File:Alpine-kernel-install.png\|600px]]~~

	~~After rebooting, verify the newly-installed kernel version:~~
	~~<pre>~~
	~~echo "kernel: $(uname -r)"~~
	~~</pre>~~

	~~[[File:Alpine-kernel-new.png\|320px]]~~

	~~=== Revert ===~~
	If needed, revert to the previous backup kernel package we identified earlier. This example shows how to revert to the previous "alpine-lts" package after removing the newly-installed "alpine-lts" (both are named "alpine-lts" yet refer to different versions/locations):
	~~<pre>~~
	~~apk list linux-lts # newly-compiled kernel installed~~
	~~doas apk del linux-lts # newly-compiled kernel from file~~
	~~doas apk add linux-lts # previous kernel from Alpine repo~~
	~~apk list linux-lts # previous kernel installed~~
	~~doas reboot~~
	~~</pre>~~
