The 2012.11.01 ISO image mainly contains minor bug fixes, cleanups and new packages compared to the previous one:
- First media with Linux 3.6
- copytoram=n can be used to not copy the image to RAM on network boot. This is probably unreliable but an option for systems with very low memory.
- cowfile_size boot parameter mainly for persistent COW on VFAT. See the README file for details.
