I think it would be useful to supplement the
reinject command with an automatic
mode which calculates the checksum of the source file and injects the file if it
is known to the repository (without the need to provide a destination filename).
In addition, this could be done recursively if the user provides a directory to
inject. All this can probably be done already with some plumbing, but a simple
reinject --auto (or
scavenge, if you like) would be a nice addition.
Of course this would only work for the checksum backends.
Example use cases would be:
- Recovering data from lost+found easily
- Making use of old (pre-git-annex) archival volumes with useful files scattered among non-useful files
- Sneaker-netting files between disconnected git-annex repositories
