Alpine Linux
small, simple, secure
musl libc, BusyBox, OpenRC init

Install in Quick Mode

Boot from the installation medium, log in as root, and run the setup script with option -q

$ setup-alpine -q

Install to disk

$ setup-disk -m sys

Reboot

Custom Partitioning

Run the setup script until Disk & Install and stop right there (Ctrl+c)

$ setup-alpine

Install to disk without creating the swap partition

$ setup-disk -m sys -s 0 /dev/sda

or no swap and also set /boot size (in MB, default 300)

$ export SWAP_SIZE=0

$ export BOOT_SIZE=500

$ setup-disk -m sys

Post-Installation System Configuration

Base system

$ setup-keymap

$ setup-timezone

$ setup-interfaces

$ setup-ntp

Host name

$ setup-hostname

$ hostname -F /etc/hostname

Root and user accounts and passwords

$ passwd

$ setup-user -a

Option -a adds user to admin group wheel and installs doas

Secure Shell access (SSH)

Essentials

Enable community repo

$ setup-apkrepos

Select (c) Community repo enable or edit /etc/apk/repositories and uncomment the corresponding line.

Install man pages

$ apk add docs

Package docs is a metapackage that pulls in mandoc.
