FYI, the AFS filesystem provides something akin to this. It expands an
"@sys" in a pathname into a unique system type. Ie if you have a link
bin -> .bin-@sys
and have a directory named .bin-i386_linux1 and .bin-sun4_54 (for
example), then the AFS daemon(I think) will expand the proper name at
runtime. This behavior does work in the Linux port of AFS, although only
on AFS volumes. I don't know how hard it would be to adapt to arbitrary
filesystems. The developer's name is Derick Atkins, warlord@mit.edu.
There is also a "linux-afs" list at Mit...
