Ah, I think I see now what you mean. It's not really comparable, though.
"Normal" filesystem translators actually implement the filesystem that
stores the symlink -- while the proxy only exposes the underlying

Note that the symlink translator exsists for the sake of filesystems
that do not know about symlinks (fatfs for example), or to allow setting
them as active translators on a readonly filesystem. In normal cases
(like ext2), the symlinks are handled specially by the FS server instead.

If you look up a symlink on a file system that doesn't natively suppport
symlinks, it will handle it like any other active translator, i.e. it
should give you a retry notification.

Ah, I see... I wasn't aware of this thing. Thanks a lot for the
