Re: Trying to set context on a FIFO for nut_upsmon_t process

Robert,

If your application fails due to selinux policy, you could check
/var/log/audit/audit.log.
If the audit.log contains denial, please post or attach the log here.
It should show what kind of policy your application needed in order to
execute it.
