Shoot, thanks.  I can't stand that when command line switches are 
contrary to
directives in a config file.  Yeah, it was just for testing tho, I'm 
trying to see an actual
error report, namely my '77 pending sectors', since then I'll be able to 
know
right away if I've fixed it, rather than having to wait about 12 hours 
for the next
report.  Or, some way of getting that report directly from smartd itself.

Yes.

Ok, good to know, I presumed the whole show came from one source. 
Knowing that,
I'd forget smartd-runner and just access error messages directly if I 
knew how.

Yeah, it's what I expected, still I'd like to be able to fire up an 
actual test at will.

Complicated!  Ok, I'll take a look.  No way of intercepting these LOG_* 
messages?

Ah!  But I very much  want to see it if it increased!  If the pending 
sectors went above 77
that's new information so these blocking directives are not what I want 
per se.

Thanks, that's more stuff to chew on.
