That's true.  New Alpha models are introduced too fast for glibc to
follow.  Actually, it would be quite possible to include the missing table
entries in Debian-built libc, if we knew what they should be (that is,
if we had the full list of system name -> system type mappings).  The
alternative approach is to create that hackish "link" during the base
install, which I think is less attractive.

What does your /proc/cpuinfo say about your system type, by the way?
