I am under the impression that sha256sum pings the distro side of things and reads "THEIR" hash file for my .img and gives me that info in a hash-printout in my term.
If so, how I am able to get that info without being connected to the network?
I tried it a few times without the network connected, neither wifi or ethernet. Both times, with different images in different term's, I got a response. It makes me think the command is just reading MY "sha256sum.sha file that downloaded with the image. Maybe it is, either way, seems strange.
