Currently, we have a large number of dac_override capabilities in Fedora SELinux policy
 
 
$ sesearch -A -p dac_override -C |grep -v ^DT |wc -l
 
387
 
 
and most of them are no longer needed. dac_override is very powerful capability which allows a process to ignore Discretionary Access Controls including access lists.

The major benefit to Fedora is increased security. Since, no process will be allowed to read files/directories with a different ownership in the defined SELinux namespace. Meaning, if you are running a service which is exploited and has wide SELinux rules, you won't be allowed to pass DAC check.
