Ah...I've often wondered what changes Debian makes to mainline kernels in the kernel-source packages, and I guess we have our answer :) I guess if you're really set on making initrd-ified kernel, you'll need to get the Debian kernel source. This is a rather large download, but I'm fairly sure there is a short cut: instead of getting the full source tree, just go get the patch Debian applies to it; it'll be in the pool on your local mirror, you want 'kernel-source-2.4.20.diff.gz'. Either that, or go find the cramfs patch's upstream and download it directly. I must say, I've never really played with cramfs and initrds before, so please excuse me if I'm completely wrong :) > (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).) You can just get it from the sid section; from a quick look at it's dependencies, it appears it'll work fine on sarge or woody. -- Rob Weir <[EMAIL PROTECTED]> http://ertius.org/
