iirc it sometimes failed to set up swap with level 2.
Even now, with level 2, it seems that mkfs sometimes gets killed.
Apparently, the Linux kernel kills processes that are larger than the
amount of real RAM, even if there is plenty of swap. There is a way
to change this via some files in /proc, but I followed the
instructions someone gave me and it was still killed. :/ It would be
great if someone who had some time to look into this - I can forward
links to them.
In fact, here it is:

Unfortunately, this didn't work for me.
