if all=& in |yawn, it will delete all listeners ducts,
without notifying them about it, which seems bad,
so we migh adress that separatedly.
Also, it might be cleaner to have a separate task instead of
a flag, to have two paths for "remove me" and "remove all",
this way there won't be an option for a listener to remove all
others, and that will have to be handled explicitly.
if you're trying to tombstone at the head of the desk, you probably
don't know what you're doing. so we abort.
we keep the option to `|rm` any matching hashes in other desks since
this is something the tombstoner might not know exists in advance and is
actively blocking them from completing the desired tombstone operation.
This should no longer go into dill, but instead be controlled by drum
directly, since that's where system output gets rendered now (in the
common/default case).
wasn't properly descending into directories next to files with the same
name.
now offers to remove files that can't be tombstoned. can choose to
remove the file at the head of the current desk or from the files on
other desks sharing the same hash.
This modifies the %rake task in %gall, to select what kind of
subscriptions we try to close:
=mode %o: kill old pre-nonce subscriptions
=mode %z: kill old pre-nonce subscriptions, including sub-nonce = 0
=mode %r: kills all stale resubscription flows
It also adds a dry-run option to both tasks (%kroc in ames, %rake in gall)
It's often useful to |merge a desk, but if you're still getting updates
from your sync source, you may get overwritten in the future. In this
case, you want to merge and clear the sync source. With this change,
you can do this with:
```
|install ~ship %desk, =once &
```
