The indexes are contained in the image directories in your vault.  If you
expire an image, the index along with that image will go away.  Try it and
see for yourself.

Somewhere....I wrote a 'dirvish-makeitexpire' script.  It's crude, but it
works for me.  It's on the dirvish wiki site somewhere.  It just parces the
summary file and changes data to ensure that the image gets marked for
expiration. I still have to run dirvish-expire to DO the expiring...

Two words.   SYMLINKS!

Ok..so that was one word.

Why not just SYMLINK your 'daily' backups to the correct 'dirvish image du
jour'  You can have all the updates you want with the stability of a unified
directory.

Symlinks are our friends.
