mkinitfs

This is the initramfs generator for Alpine Linux, including support for apk and Alpine Diskless boot.

Dependencies

To compile manually, you need to have the following build tools available:

• make
• gcc with musl and kernel-headers

nlplug-findfs will link against the following libraries (runtime deps):

• libkmod
• libblkid (from util-linux)
• libcryptsetup

To run the tests you need:

• kyua
• lddtree

Installation

Build mkinitfs via make and install it via make install. The installation honours the DESTDIR parameter to overwrite the sysroot path.

For testing, its not necessary to install mkinitfs into your root file system.

Tweaking

The Makefile is kept slim and debuggable.

Testing

Run make check to run the tests.
