  It doesn't work with multiple files.  Perhaps in 2.x this will be
easier to do.

  You cannot use wildcards.  radrelay reads one file, and one file only.

  Linux doesn't do NFS properly.

  Sun wrote NFS.  The Linux people disagree with how it's supposed to work.

  Storing log files to NFS is a terribly bad idea.  If the NFS mounts go
away, then so your RADIUS server will block.  It may not come back, too.

  Use radrelay to copy accounting records from local disk on one machine
to another machine.
