If the image building process is interrupted partway through, or the
machine is not there, the dirvish process will not complete and add
an entry to the $VAULT/dirvish/default.hist file . The last valid
entry in this file will be --link-dest 'ed to the next image made.
Yes, there will be a stub image created if the machine is not there,
with a log file and summary and empty tree. That is all typically
under 20KB, so it will not fill up your disk very fast. However,
if a partial backup is done, you will end up with a partially filled
tree that will not get expired. You might take a look at
.. for a script by Jason Cater and Matt Munnich that cleans up these
old images. I have not tested this script myself, but please do so
and let us know how it worked for you. If enough people tell me it
works, it will be added to 1.3 and later (though it would be nice to
get it rewritten in Perl).
