- backup:restore:full refuses on an installation with more than one user
and asks before it starts (--force skips both, also to rerun after a
failure halfway), and warns when the snapshot's database dump was not
one consistent transaction.
- backup:user:restore --mode=replace asks before deleting an existing
account; non-interactive use needs --force.
- The recovery kit file is created owner-only and never over an existing
file or symlink; backup:key:import shows the deletion delay it read from
the kit.
- Adding a location through the web API needs password confirmation, like
removing one.
- Key derivation parameters from a kit or repository config are bounded,
and a stalled network stream no longer spins at full CPU.
- Floating-point columns are dumped exactly instead of with 14 digits.
