Extract tar.gz archives from susestudio

[rominf]

SuseStudio generates tar.gz archives for preload usb images. Imagewriter silently writes those archives but this of course produces unbootable usb flash drives.

I propose to automatically extract those archives. Meanwhile I'm using this:

#!/usr/bin/env fish

tar xf $argv[1]
set raw (echo $argv[1] | sed 's/preload\.raw\.tar\.gz/raw.install.raw/')
imagewriter -f $raw
rm $raw
