-TODO
-----
-
-* implement missing options (--grub, --kernel, --initrd, --squashfs, --uninstall)
-* validate partition schema/layout: is the partition schema ok and the bootable flag set? (--validate?)
-* provide --create-partition option?
-* implement logic for storing information about copied files -> register every file in a set()
-* the last line in bootsplash (boot.msg) should mention all installed grml flavours
-* code improvements:
- - improve error handling wherever possible :)
- - use 'with open("...", "w") as f: ... f.write("...")'
- - simplify functions/code as much as possible, especially:
- Too many local variables
- Too many branches
- Too many statements
-* graphical version? any volunteers? :)
