I disagree with your perception of the "right thing".  See Paul's responses on 
this thread - they are spot on.

The only thing I might add is that virtually the only situation in which I can 
see the most recent image being removed at an undesirable time despite good 
expiry rule configuration, is for instance when I come back from a few weeks 
holiday and turn on my home PC (which also seems to have been Tony's 
problem).  I won't even get hit by that though since my cron jobs basically 
do "dirvish-runall && dirvish-expire" which makes sure that all backups run 
successfully at least once with the most recent image still present.

See above: invert the runall/expire order.

Also, make sure retention periods are higher than the longest expected time 
you will go without backing up.  What's the point in only having a recent 
backup if the file you want to restore was in older ones which have been 
expired?
