Useful LXD commands

Summarized from https://stgraber.org/2016/03/19/lxd-2-0-your-first-lxd-container-312/.

Interestingly, the LXD command line client is named.... lxc!

List available containers

lxc image list ubuntu:        # ubuntu: is officially supported image source
lxc image list images:        # images: is an unsupported source

Technical exploration – BusyBox and the art of the chameleon binary

After using BusyBox for a long time in several custom Linux projects (BusyBox/Linux), one question kept coming back to me: How can a single executable transform into many others, simply by changing its name?

Let me explain: If you rename the busybox binary to ls, it behaves like the ls command. Rename it to cat? It does cat. Same for echo, mkdir, etc. In /bin, all these tools are actually just symbolic links pointing to a single binary:

	#include <stdio.h>
	#include <stdlib.h>
	#include <string.h>
	#include <dlfcn.h>

	int main(int argc, char** argv)
	{
	void *handle;
	void (func_print_name)(const char);
