It is so amazingly useful to spin up a fresh VM in under 10 seconds. It makes reproducing issues in a clean environment so much faster.
And there's no question as to whether the issue is affected by a chroot, or dockerization, or running in a different kernel namespace which has different permissions. No, it's s real VM, running on a real CPU.
And when I close the program (the terminal, bowser or what have you) everything gets automatically cleaned up.
I ❤️ you, #QubesOS
