Saw the followup post, glad to hear its all running well. I created my VM using virt-manager with a raw disk image and UEFI firmware rather than the default qcow2 format with BIOS. I keep the image size down to 32 GB to save time when imaging. Install proceeds as usual, make sure fstab mounts disks by UUID, Debian does by default in my case. When everything is configured, dd the raw disk image over to the target disk, do the rituals to make it bootable, and consider configuring new partition UUIDs.


Minimal delay between a program releasing new features or bugfixes and you getting to use them. Even as an avid Debian user, sometimes I get bummed out when they freeze a package for release right before a feature I would have really liked makes it in.
As for security, there’s not a huge difference I’m aware of. On Debian, features stay where they are, but maintainers will backport just the security fixes of each package to the current stable release.
