This project provides script for making customized https://alpinelinux.org/[Alpine Linux] disk images for virtual machines.
It’s quite simple (250 LoC of shell), fast (~40 seconds on Travis CI including Travis VM initialization) and requires minimum dependencies (QEMU and filesystem tools).


== Requirements

* Linux system with common userland (Busybox or GNU coreutils)
* POSIX-sh compatible shell (e.g. Busybox ash, dash, Bash, ZSH)
* qemu-img and qemu-nbd (automatically installed by the script if running on Alpine)
* e2fsprogs (for ext4), btrfs-progs (for Btrfs), or xfsprogs (for XFS) (automatically installed by the script if running on Alpine)


== Usage

Read documentation in link:{script-name}[{script-name}].
See link:.travis.yml[.travis.yml] for Travis example.

You can copy link:{script-name}[{script-name}] into your repository or download it on demand, e.g.:

[source, sh, subs="+attributes"]
wget https://raw.githubusercontent.com/{gh-name}/v{version}/{script-name} \
    && echo '{script-sha1}  {script-name}' | sha1sum -c \
