[pca] PCA return codes

It's for the whole cluster. A process (pca, in this case) can only 
return one exit code per run, so it can't provide information about 
single patches.

A sample script could look like this (untested!):

   #!/bin/sh

   /path/to/pca -i missingrs
   x=$?
   test $x = 1 && echo "Unknown error"
   if test $x = 4 -o $x = 5
   then
     echo "Reboot required/recommended. Reboot now?"
     ...
     /usr/sbin/init 6
   fi

Hope that helps.

Thanks for that!
