A ranted on my blog about why I don't like Docker. Or Podman.
@liw Have you tried the guestfs tools for manipulating VM images?
I’ve had fairly good luck with creating a base image then using guestfs to modify it for new VMs. This has sped up my VM deployments quite a bit.
@jollyrogue I know of guestfs, but for reasons I've forgotten, I didn't like it, and don't use it. I don't argue against using guestfs, and if you're happy with it, good.
I've written my own tools that I'm happy with.
