The question “which physical device contains the OS?” may not have a
simple answer:
* “physical device” can have multiple layers of abstraction involved, so
it's somewhat arbitrary which one you pick as “physical”.
* “the OS” can be on many devices, so you need to pick which part of the
OS you're interested in.
A question with a simpler answer: “which device is currently mounted
as the root filesystem?”, may serve as a useful proxy. Here is one answer:
$ mount | grep 'on / '
/dev/sda1 on / type ext4 (rw,relatime,errors=remount-ro,data=ordered)
Does that proxy question suffice?
