I was being snarky (but was quite serious that I had tried to understand
tahoe backup and not known about this revalidation behavior).
I think it's a serious bug that 'man tahoe' followed by 'man tahoe-foo'
(as directed by 'man tahoe') doesn't have basic usage instructions (in
my installation, there are no man pages at all - apologies if that's a
packaging bug on my part). Users should not be expected to have a
source tree, and all the documentation that they need should be
installed and in binary packages (as man pages, or a short man page and
an info file).
Thanks for the pointer.
I have avoided tahoe backup because 1) it failed to back up for me once
and 2) I think the filesystem and the backup control system should be
orthogonal, and I haven't seen a good argument why tahoe doing a
roll-your-own backup program that is tied to the filesystem is a big
enough win to overcome the cost of the coupling.
