How does it pick between min and max?

it picks a value in between leaning towards max if space is available, but it will never allocated less than min

what does it mean by an iso9660, I guess virtual cdroms are not so much used as an option, also newer ISO support something called File System Transposition and are not really supposed to be dd'ed to a disk

I think we need to fix this one way or another, but I'm confused a bit about the method. We should document what is the supported method of moving an ISO to a USB stick, and the one we support here

ok, we have a plan going to support two things:
ddthe ISO to the USB stick (already works without issues)- copy the ISO contents to the VFAT usb stick (need some changes to support that)

I was basing this off what I was seeing on my physical hardware in the various tests. It only seemed to work when the detected filesystem was iso9660 but I didn't exhaustively test what's available.

When I dd the iso to usb the usb drive showed up as sda1 and I don't think the cache was used during provisioning. I can test again if you think this should work.

I think you did something wrong there, we tested with ISO, and it works and is detected. we have another way coming up, I will update your PR once it's tested

If we're going to make this work with USB drives before 1.9 comes out then we can close this PR and focus on one with alternate instructions for USB. |

@rothgar I'm going to update this a bit with recent fixes and push back to your branch. |
