I'm running the most recent version of Morello Linux. I understand that it's based on Debian. What I need is a way to "debootstrap" a small instance of Morello Linux. Is debootstrap supported for Morello Linux?
Once you've booted Morello Linux you're running arm64 Debian and should have network access, so any standard Debian command like debootstrap should work as you're used to. Just make sure you've got enough disk space for creating the new chroot.
