suggestion -- improve use of USB media

[SaintDanbert]

Please consider the following features that might improve the use of USB media.

1. Accept a --label option and set that label at the end of the 'dd' processing.
   For my part, I use meaningful labels so that I can keep an index of the content that is on the various USB media devices that I have.

2. Create a "distro space" and a "data space" on the bootable USB media device.
   Given that USB media devices are now available with much more capactity than is required even the largest distribution, it might be nice to have an end-user "data space" on the device in addition to the "distribution space." I realize that not all USB media will support multiple partitions, but bootiso could detect this and report if this option cannot be implemented.

Hi @SaintDanbert
Thanks for your participation.

1. --label option already exists but only works for mount-rsync mode (and not dd indeed).
   So you would like to have it available for dd mode ? There is some work, since some ISO image files contain multiple partitions☆. So I have to identify the right partition first with some heuristics (the biggest? the non-ESP one?)
2. This is feature request Bootiso should allow creation of a persistent data partition #1. I will definitely implement this in a near future :-)

☆ See for example the output of fdisk -l manjaro-architect-17.1.11-stable-x86_64.iso. You'll see an ESP (EFI System Partition) at second position.

Closing now. Feel free to open a ticket for --label to work with dd-mode :-)
