This is where, as a sysadmin, you need to invest just a little time and 
effort learning the system. Honestly, the vast majority of issues are 
trivial to solve if you just spend a few hours reading the docs/guides, 
and even if you really can't be bothered there are kind folks on this 
list (and others) that will likely solve your issues for you. How is 
that not worth the extra security SELinux affords?
