However, a "restorecon -vR /usr/local/Adobe" results in "/etc/selinux/targeted/contexts/files/file_contexts: Multiple different specifications for /opt (system_u:object_r:home_root_t and system_u:object_r:usr_t). /etc/selinux/targeted/contexts/files/file_contexts: Multiple different specifications for /opt (system_u:object_r:home_root_t and system_u:object_r:usr_t)." and no file contexts changed. I am clueless about the details of selinux. Is this a bug in the policy script or might this be a failure in my installation. Don't know if it matters but I upgraded from FC4.
