Exactly.

I don't know for sure when the system event for expiry is called (before 
or after the file is gone); however since the delete will just change 
the recording group to Deleted, the file will still exist.  If this is 
also the case for expiry, you should be able to just have the system 
event pass the %FILE% , and then use something like:

find -L /path/to/symlink/dir -samefile /path/to/original.file

I don't know for sure if %FILE% includes the path, but if so, you're 
golden.  If not, you'll have to find which path the recording file is 
in--you could do that any number of ways, but the easiest would just be 
checking (i.e. with an "if [ -e /path/to/original.file ]" type 
construct) each directory in each of your Storage Groups (even 
hard-coded into the script).

If the expiry event is called after the file is gone (or if you just 
want to do some occasional cleanup, in case something was missed), you 
could just do:

find /path/to/symlink/dir -xtype l

(where that's an ell, as in link, after -xtype).

You can test your script with a -print at the end of your find commands 
to see what was found.  Once you feel comfortable, you could do -delete, 
instead.  Note, however, if you do an -xtype l test with -delete and you 
happen to have some unmounted storage, you may delete links to valid 
(yet unavailable) recordings.

Feel free to post something here, and I'm sure you could find some 
others who would have fun testing and commenting and improving your 
script, and you can put the script in the wiki where others could use 
it, too.
