I'd guess it's going to cost more of your time (which is also money) to
work out a software solution than to buy another disk! False economy?

Why not? If you use the --time option, you can convince dirvish-expire
it's running in the future. Specifically, you can tell it it's running
after the expiration time stated in the summary files. You can restrict
it to a particular vault.

It looks at the Expire line. You can just edit that if you wish.

Don't know :(  Personally, I just use rm when I occasionally need to
remove a backup image.
