You need to bear in mind that a symlink of the form you half-suggested
(ie, including '$HOSTNAME' or whatever it was) won't work; I think you
need to think about symlink farms to a machine-local
/local/home/user/.foorc for your .rc files; this isn't ideal, but works.

The filesystem stores all this little lot numerically, and for display
purposes, the local databases (PAM / /etc/{passwd,group} / NIS / LDAP /
whatever) are consulted.

There is a mapping daemon the name of which I forget for NFS, but that's
not foolproof either.
