An question I never found an answer to, when I last asked it in I think 2019: I’m already in a Linux, of whatever flavor, is there a way for me plug a new, bare hard drive in and say “turn this new drive into a bootable install that’s just about identical to the machine I'm currently using?" I don't necessarily mean bit-for-bit "identical" - clone meaning "working, identical boot process, same .debs installed" would be a solid start.
