Technical Analysis of Linux Binary Compatibility Using musl libc and dlopen

For a while now, it's been very easy to reliably ship command line software & servers for Linux, just run go build and out pops a single static binary that will run on any Linux distribution running kernel 3.2 or later

The holy grail of Linux binary compatibility is being able to ship a single binary that works on any Linux distribution, regardless of the libc version or other system libraries

musl libc is designed to be lightweight, fast, and standards-compliant, but more importantly for our purposes, it's designed to be statically linked without any runtime dependencies

dlopen is the dynamic loading mechanism on Linux that allows programs to load shared libraries at runtime, which is essential for plugin systems and modular architectures
