Jonathan,                                                                       
                                                                                
At "post" time, perl should be available, you could try a one-liner.            
                                                                                
Have a look at /etc/logrotate.d/syslog -- if it's the files                     
mentioned in there, it might be an option to just put your                      
"compress" directive in there. As an example, with perl you could:              
                                                                                
perl -pi -e 's#endscript#endscript\n\tcompress#;' /etc/logrotate.d/syslog       
                                                                                
or something similar, which might do the trick.                                 
                                                                                
Hope it helps!
