Thanks for your PR!
Could we do | "${have_pv:-cat}" | write_do_disk to show the same stats in both cases?

it seems pv needs to be the first stage in the pipeline in order to include an ETA; when its streaming between stdin and out it doesn't know the total size...
Fitting it into the other places would obviously be easier in stream mode...
So I guess its code simplicity (streaming) vs features (first in pipeline) - I'm not tied to having an ETA so do you have a preferred approach ?

Maybe we should also limit the use of |

Or make it opt-in via an extra flag? |
Doh! Yes will do. |
optionally use PV to provide feedback while writing to disk
If we find pv is installed on the system running flatcar-install, use it to report writing imagefile to disk
How to use
Install from an image file (not a URL)
This is for feedback - I've only fixed the path I'm using (install from file), happy to extend this to the download path if requested.
