Although logrotate is happy to continue with the logging process if a file 
doesn't exist (given "missingok"), it will die mid-job if there is a globbing 
error even if missingok is set. For instance, if you ask to 
rotate /priv/log/somedir/*.log and the somedir directory doesn't exist, 
logrotate will exit with an error even if "missingok" is set for that glob'd 
file.

Possible ideas for fixes:

1) have logrotate respect missingok when glob errors are encountered
2) add another primative (e.g. missingdirok)
