I use Alpine linux on my second computer (Raspberry Pi 3 Model B+). This document lists the steps used to setup my system. All the refrence links can be found at the bottom of this document.
The first step is grabbing a RPi archive from the Alpine Linux downloads page.
First, check the device name. Most likely going to be /dev/mmcblk0
Now we can create two partitions on the SD card. One for boot, another for everything else.
Now we gotta format the partitions we just created (make sure to check the name of partitions using 'fdisk -l'):
In my case partitions were '/dev/mmcblk0p1' and '/dev/mmcblk0p2' (may need e2fsprogs for ext4 formatting)
mkdosfs -F 32 /dev/mmcblk0p1 mkfs.ext4 /dev/mmcblk0p2
Create a directory for mounting partition 1 and extract the Alpine archive in it:
mkdir /mnt/myalpine mount /dev/mmcblk0p1 /mnt/myalpine cd /mnt/myalpine tar xvfz ~/Downloads/alpine-rpi-*-aarch64.tar.gz
Due to a bug, it is recommended to add a file named 'usercfg.txt' in the partition. The second line enables audio. With following data:
Un-mount the partition:
Hooray! The SD card is all set to boot and start installation.
Insert the SD card into RPi. Connect your display and keyboard. Power everything up!
Login using 'root' (requires no password)
We will use Alpine's default setup script:
Mount partition 2 and install alpine:
mount /dev/mmcblk0p2 /mnt export FORCE_BOOTFS=1 setup-disk -m sys /mnt
Remount partiton 1 and cleanup:
mount -o remount,rw /media/mmcblk0p1 rm -f /media/mmcblk0p1/boot/* cd /mnt rm boot/boot
The right place for boot is in partition 1:
mv boot/* /media/mmcblk0p1/boot/
We don't need boot in partition 2 now:
rm -Rf boot
A directory for partition 1 on next boot:
A link for boot from partition 1. Don't worry about error.
ln -s media/mmcblk0p1/boot boot
echo "/dev/mmcblk0p1 /media/mmcblk0p1 vfat defaults 0 0" >> etc/fstab set -i '/cdrom/d' etc/fstab set -i '/floppy/d' etc/fstab cd /media/mmcblk0p1
Indicate the root filesystem is on partition 2
sed -i 's/$/ root=\/dev\/mmcblk0p2/' /media/mmcblk0p1/cmdline.txt
The installation is now complete, you can use 'poweroff' to continue steps after installation later or use 'reboot' to restart system and continue with post-installation steps.
Enable Software Clock and Disable hardware clock
rc-update add swclock boot rc-update del hwclock boot
Enable checking time using Network Time Protocol
apk update apk upgrade
Now any applications of liking may be installed. My setup may be found in 'Doc/My Configurations' in this website.
