It should really be done in userspace. And ripped from the kernel.

The output is useful when debugging boot problems on systems whose 
rootfs is on the network. So I think the patch is ok.

However, it would be useful to make the parameters available to 
userspace for use by boot scripts etc. A proc file listing variables and 
values in /bin/sh syntax would be easy to use. I've been meaning to do 
this for ages so I'll roll a patch.
