[pca] Logging

It's not forcing anything on anyone, and high flexibility usually is a 
good thing. But at the same time an overload of options can drive people 
away before they even start to use it. Lately I'm with Antoine de 
Saint-Exupéry, who said: "It seems that perfection is reached not when 
there is nothing left to add, but when there is nothing left to take away."

That's strange. pca does log both successful and failed attempts to 
syslog, to the same facility/level. Please try that again.

I appreciate that. And it's one more step towards convincing me that 
more detailed logging is necessary. I'm just not there yet :)

Thanks. Ok, now that's exactly what I would not want a log look like. At 
least half of the messages don't seem to contain real information. And 
with that many failures, errors, warnings etc. I definitely would do my 
patch installs interactively, watching the output on screen.

In my experience (and not to sound arrogant) with pca it really boils 
down to one "successful install"-message per patch, so for 99% of the 
pca runs I wouldn't know what more information to include.

Martin.
