Looks like the attachments didn't make it through. Folks interested in this
can just send me email and I'll make them available via some other channel.

No shiny hero here. Attached is an updated version of vdu (called vdu-new)
that counts both inodes and diskblocks. It is based on vdu.c from
util-vserver to walk the directory tree. The main change is the handling for
files with hard linkcount > 1. It maintains a table of such files and only
accounts for the diskblock size if it can find all hardlinks. Otherwise, it
only accounts for the inode that are used within the /path/to/vserver.

Here is a simple example:

sudo vdu-new /vserver/v_mef
12966 315544 132251 /vservers/mef
where the numbers are inodes, blocks, and kb.

Hopefully this is useful. Comments and feedback are greatly appreciated!
