Cramfs compresses each fs block individually, if compressing a big image
or tarfile due to the fact that it is bigger than a fs block it will get
better compression.
An alternative to cramfs is to use romfs for the initrd, compresses it
with gzip -9 and uncompress to tmpfs (or ramfs), but its a tradeoff, you
would save disk space due to better compression and smaller kernel, and it
would be faster from memmory, but it would also use a lot more memory
which could be a critical factor.
Personally i think cramfs is the best solution for lowmem installs and
romfs.gz/tmpfs is best for normal installs.
