Tried to decide if I should look into #pasta instead of #slirp4netns. Looked at their webpage and found a long list of features. Nice.
Looked for a man page for the pasta command, but it was nowhere to be found on the webpage. Instead I could watch a 10 minutes long video showing 3 terminal windows and a window with a scrolling text explaining what happens in the terminal windows.
That is a thanks, but no thanks from me.
