There is little(?) reason to compress the -extra archive, but some
there are some good reasons why it should be left uncompressed:
1) decompression increases boot time
2) selecting exotic formats (e.g. lzma or zstd) can actually
increase the initramfs size since you now have to include
support for those archive formats
In the future this could be made configurable...
mkinitfs is a tool for generating an initramfs. It was originally designed
for postmarketOS, but a long term design goal is to be as distro-agnostic as
possible. It's capable of generating a split initramfs, in the style used by
postmarketOS, and supports running boot-deploy to install/finalize boot files
on a device.
Building
Building this project requires a Go compiler/toolchain and make:
$ make
To install locally:
$ make install
Installation prefix can be set in the generally accepted way with setting
PREFIX:
$ make PREFIX=/some/location
# make PREFIX=/some/location install
Other paths can be modified from the command line as well, see the top section of
the Makefile for more information.
Tests (functional and linting) can be executed by using the test make target:
$ make test
Usage
The tool can be run with no options:
# mkinitfs
Configuration is done through a series of flat text files that list directories
and files, and by placing scripts in specific directories. See man 1 mkinitfs
for more information.
