But mkinitrd (which is the _only_ thing that people tend to use to write 
initrd's - is there even anything else) has already been doing this for 
years, as has been pointed out several times.

This is why I harped on the fact that you already rebuilt your initrd 
image.

So this really isn't a "updated immediately" issue, afaik. Googling for 

	mkinitrd MODULE_FIRMWARE

shows a patch from two years ago as the #1 hit in order to make the 
aic94xx driver work.

Loking down a bit, there's a hotplug discussion from early 2005 (gmane 
says "3 years, 20 weeks, 3 days, 6 hours and 39 minutes ago" in the 
header).

Quite frankly, if it's still a problem, there's simply something _wrong_ 
with the distribution. And yeah, maybe people need to update their kernel 
building tools.

I already pointed out how the kernel development team quite often says "we 
will no longer build with gcc-.xyz because it's too old and buggy". The 
build tools requirements are simply *different* from the runtime tools.

If it's literally just an issue of an mkinitrd that is too damn old, why 
don't we just make that test at kernel build time. *EXACTLY* the same way 
we test for compilers that are too old, and refuse to build with them?

(And no, I have no idea which version we should test for. In fact, 
mkinitrd seems to be singularly hard to test versions for, in that it 
seems to want the user to be root even just to give the version output. 
Ooh).
