While it's a nice idea, it may not be necessary.

If you have 4.3BSD or a recent SunOS, your find command has the option
-xdev, which prevents it from looking at files in other filesystems
(hard links can't cross filesystems), so you can say

	find <root of filesystem> -xdev -inum <inum> -print

To find the root of the filesystem, just use df on the file and
pipe the output through an awk or sed script to extract the name
(watch out for df printing long names, especially NFS filesystems,
since it will produce extra lines).
