I haven't caught up on even important changes in #nixos , #initrd has stopped using #dropbear
but why ? Though?
alternative doesn't sound very cool either
virtual machine shares its /gnu/store with the host, your new VM takes up far less space than you might expect! On my system, the disk image is just 2MiB! All the heavyweight stuff (qemu, the kernel, #initrd) is shared among all my up-to-date VMs, and the state files all live elsewhere and can be managed directly from the host! You can also choose how much memory and how many cores your service is allowed to use #guix https://benwr.posthaven.com/magic-immutable-ish-virtual-machines-with-guix-and-tailscale
