The syntax for Multipass looks eerily similar to LXD syntax. Are these projects related, or completely separate?
The Multipass folks based most of their CLI on what LXD did.
Multipass on Linux also actually just drives LXD behind the scenes these days.
The main value of Multipass is if you also want VMs using the exact same workflow on MacOS or Windows as it will provide you with Ubuntu VMs on any OS.
