[tahoe-dev] what's the impact of [4272]

[Zooko O'Whielacronx]

Brian:

How should I describe the impact of this patch in the NEWS or ChangeLog?

http://tahoe-lafs.org/trac/tahoe-lafs/changeset/4272/

I don't understand backup well enough to know if this meant it would
generate a new Tahoe-LAFS directory for every directory on every
backup, or if it would do so only in some special case involving
metadata or other conditions.

Regards,

Zooko
