Bug#464938: d-i on i386 with 16 MiB RAM (using swap)
Using bzip2 doesn't save RAM, but it saves space on the root floppy.
(If you add all three ide modules on it, you would normally (using gzip)
end up with image bigger than 1.44 MB).
Therefore I suggest to compress initrd on the root floppy with bzip2,
which claims for using a bzip2 decompressor on the boot floppy,
insted of the gzip one.
