This I did not know. I'm not sure if it will really matter or not. The
initramfs is already gzip -9'd. I have a list of modules that are required
for stage 1 which pulls in the dependancies for those modules. It does
currently fit on a single floppy. I'm using a upx compressed kernel, a gzip
-9'd initramfs, kernel is compiled with -Os and I'm using a -Os compiled
busybox statically compiled with uclibc. When it's all said and done, I
have less than 10kb available on a floppy. I thought it was quite an
acomplishment getting all that one 1 floppy.
