There's room for the sub-architectures to combine stuff. I think there
is work going on to do that (at some level).

I'm not an authority by any means, but every time there is a new device
released (which is often) you get a new file under some mach-xyz
directory, or some large modification to an already existing file. Plus
a config file potentially. It's a little bit like the wild west, and
seems way wilder than x86 every was.

I think from the sub-architecture maintainer perspective the pain is all
hidden behind the Linus curtain , or RMK curtain or the some other
maintainer curtain. So we don't really talk about it that often. I
thought you we're totally happy with the situation ..

If you have some idea's for fixing things, I'm all ears along with my
faithful sub-architecture maintainer brothers.
