TODO
----
-* install memtest, dos, grub,... to /boot/addons/
-* copy grml files to /grml/
* implement missing options (--grub, --kernel, --initrd, --squashfs, --uninstall)
-* code improvements:
- - improve error handling wherever possible :)
- - get rid of all TODOs in code
- - use 'with open("...", "w") as f: ... f.write("...")'
- - simplify functions/code as much as possible (move stuff to further functions) -> audit
* 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? :)
