Sounds like someone is still running genvmunix.

It's quite frightening that you would compare a 486 running Linux to
an Alpha running Digital Unix. It tells me that you're quick to
criticize without checking the facts first. Digital Unix is 64 bit,
Intel Linux is not. Alphas are very much RISC-based, we all know that
the i486 is not. So, not only do you have a bloat resulting from CISC
vs RISC, but you're basically doubling the size of binaries by going
from 32 to 64 bit (I don't think you'll want to try compiling the
kernel with -xtaso). Apples and Oranges, as they like to say.

There are plenty of other operating systems out there that manage to
meet, if not exceed the "bloat" of Digital Unix's kernel. I suggest
that you have a look at AIX, HPUX, Solaris, etc.
