Yes, I could hand-code it myself. But the question is why isn't such a boolean pre-defined by default in Debian? Am I really the only one who sometimes (like once a year or so, maybe) takes a disk (aka µSD card) out of a machine, mounts it on another, and then chroots into it to perform some administration tasks "offline" (tho sometimes it's really more online: one of the cases where I did it was because the main machine didn't have access to the Internet, so I performed the updates by mounting the rootfs on another machine and used aptitude there)?
