Arg. Even uname -m reports the wrong thing on my DS10. :-( Havn't 

checked the AS1000 yet.

If we want it to behave like i*86, which does somerthing like:

	uname -mpi
	i686 i686 i386	

should Alpha report on (667MHz) DS10:

	uname -mpi
	alphaev67 alphaev67 alpha

Here's from the manpage:

       -m, --machine
              print the machine hardware name

       -p, --processor
              print the processor type

       -i, --hardware-platform
              print the hardware platform

I assume we'd keep the generic "alpha" name for hardware platform (-i),
but should the sub-architecture show up in either or both of the others?

BTW, I'm VERY interested in this area, as one can get a BIG benefit
from running packages built for a specific Alpha sub-architecture on
appropriate machines (eg alphaev56 for PWS/LX/SX, alphaev6 for DS10).

Right now, "rpm" will make you say "--ignorearch" to get ANY sub-arch
package installed; that's not right.

It'd be nice, not only if "rpm" didn't force you to say that, but also
if "rpm" OR "yum" would consider it a valid potential "update" to just
install the same version package built for a (more appropriate)
sub-arch on top of an installed generic one.

I've rebuilt a lot of SRPMS targeted for alphaev67, and I'd like to
make it easy to get a more optimal system after installing from a
generic set.

Anyone have any additional thoughts on this?

I was able uname to output for uname -mpi:
alpha alphaev56 alpha

uname -m show information returned by uname glibc call (which in turns
calls kernel.

Kernel-Bug :-P

I remember tracing that a long time ago).
The -p and -i is handled by "uname" and have some altering code for
other arches. I'll install modified version of uname and see how other
programs would like the new output. :)

Let us know!

Best,
Oliver
