MINimal Embedded sysRoot using Alpine Linux.
Let's you very quickly setup a sysroot with...
- ...any number of Alpine packages installed.
- ...running any architecture supported by Alpine.
- ...without requiring any special privileges.
As an example, on an x86_64 system, we can easily setup a aarch64
sysroot and run a command inside it like so:
~/src/github.com/wkz/mineral$ uname -m
x86_64
~/src/github.com/wkz/mineral$ ./mineral init -a aarch64
fetch http://dl-cdn.alpinelinux.org/alpine/latest-stable/main/aarch64/APKINDEX.tar.gz
