As soon as the target filesystem is available, then some of its space
could be used for a swap file:  Create a file of 150MB actual space,
then swapon that file.  150MB is 5% of the 3GB occupied by a default
install, and so is about the size of the default reserved space
within the target.  150MB is less than (1152MB - 640MB), but it is
still something.  I consider it evidence of "bloat" that a minimum
512MB swap partition is required; other reductions still are needed.

Another possibility: split the initramfs into two pieces: the files
that must be _active_ at the time that the target filesystem is mounted,
and the others.  Mount the second piece from RAM at the beginning,
but later unmount it, copy it into a temporary file in the target root,
mount it from there, and reclaim the original RAM.
