An audit log will tell me what people ran, and people generally know
exactly what they ran and may even be able to tell me that later.

I do _not_ expect people to remember the entirety of a salvage log. I
want to know after the fact that the salvager removed vnode X uniq Y
from volume Z because it was invalid due to reason Q, which the salvager
will tell me in the middle of hundreds of other messages (potentially).
If that information is only output from a 'bos salvage' command, yeah,
_some_ people might save it. Some people might not, and for some people
maybe the command output is too large to keep in whatever output buffer
to copy later, so they've lost it forever.

I can see no reason not to keep it logged.
