AFS currently has a single magic symbol, "@sys", which expands to a
system type name - something like sun4x_59 or i386_rhel4. Modern
versions of OpenAFS actually have a more-magic expansion such that
@sys can be a list (say "sun4x_59", "sun4x_58", "sun4x_57"), and a
path like arch/@sys/bin will expand to the first real path that exists
with one of the members in the list. See openafs.org for current
info; it's quite well-used today.
