[OpenAFS] salvage removed .6M files!

[rader@ginseng.hep.wisc.edu]

More information, fwiw... 

 - SalvageLog.old indicates (the initial) salvaging started 
   at 01:07:43 

 - BosLog indicates that that salvage exited with signal 15 at 
   05:00:38

 - SalvageLog indicates another salvage--the one that went 
   awry--started at 05:00:38 and completed 06:44:41

 - bos getrestart reports the server should restart for
   new binaries at "5:00 am"

It is possible the "restart for new binaries" erroneously happened,
and it kill -SIGTERM'ed the bos salvage which left the volume
in an inconsistent state that caused the subsequent salvage to
blow chunks??  (I'm under the general impression that interrupting
salvages is a bad idea.)

At any rate, I've turned off the "restarts for new binaries at
5:00 am" thing.
