Okay, I found and installed genromfs.  That got a ramdisk built.

Unfortunately, it was too big.  

Fortunately, lilo's ramdisk=xxx option solved that problem.

Unfortunately, after the booting kernel says that it found a 
romfs file system, it says:

   cramfs: bad magic


So how do I get the kernel to access a romfs initrd image?

Or is there a way to make a cramfs filesystem?

(Recall that I'm trying to build from vanilla kernel sources (2.4.20),
not from Debian-patches sources (latest 2.4.18 in woody).)

Thanks.
