Errors at the end.

The bup-wrack pool was newly-created, empty, before this backup started.
The backup commands were:
zfs send -Rv "$srcsnap" | zfs recv -Fudv "$BUPPOOL/$HOSTNAME/$FS"
I don't see how anything could be creating snapshots on bup-wrack while
this was running. That pool is not normally mounted (it's on a single
external USB drive, I plug it in for backups). My script for doing
regular snapshots of zp1 and rpool doesn't reference any of the bup-*
pools.
I don't see how this snapshot mismatch can be coming from anything but the
send/receive process.
There are quite a lot of snapshots; dailys for some months, 2-hour ones
for a couple of weeks. Most of them are empty or tiny.
Next time I will try WITHOUT -v on both ends, and arrange to capture the
expanded version of the command with all the variables filled in, but I
don't expect any different outcome.
Any other ideas?
Is it possible that snapshots were renamed on the sending pool during
the send operation?
