How much of this is because, say, udev is using shell scripts as
opposed to C? If the answer is you lose flexibility when you do it as
shell script fragments, I just spent 30 minutes with Alsadair chewing
on my ear about how udev's use of shell scripts is making dm/LVM's
life hard --- and I'll note that if we solve this problem by bloating
the kernel, you lose flexibility *anyway* since the kernel code will
be in C and not shell scripts. :-)
