I could get by with one half time sysadmin. I can't afford that so I  
spend the 20 hours a week.

MySQL is fine, I never have any problems with it. The only database  
maintenance is the flushing of old data, which is croned  
automatically. Only if the server crashes do I need to touch the  
tables. The time is in making sure all the other services findU  
depends upon are working, checking that yum updates haven't broken  
anything (for example, when imagemagick, perl, or gd are updated,  
almost everything needs to be checked) rebooting if the kernel has  
been patched (and praying it comes back up), running snort for  
intrusion detection (manually from a hidden partition only mounted  
during the test), scouring the logs for people who have found new ways  
to scrape data and blocking it, answering tons of email about findU  
and APRS in general, going through the output of the log scanners, and  
many other little things which I do not feel like spending some of my  
20 hours enumerating!
