Public bug reported:
Binary package hint: usb-imagewriter
USB ImageWriter should support compressed images. It is a good idea
because it reduces bandwdith and storage space on the servers, and
allows less disk usage on the host system to write the image out (a
650MB .img file for ARM Netbook could be made much smaller)
Since it just chains commands like "dd" through the Python script piping
compressed data to dd would be easily implemented. Certain compression
utilities (xz) will also report the uncompressed size such that progress
can be reported properly.
Should also support dcfldd if installed (or other dd clones or
improvements) such that progress could be properly reported by catching
and parsing the output of stderr from the "dd" utility used. In lieu of
that why can't imagewriter.py send the HUP signal to dd and catch
progress every second or so, so that the progress bar can be implemented
properly?
