Reported as am uncertain if bash requires this access? If you read the alert, it told you how to fix this. restorecon /etc/resolv.conf Now the question is how did it get mislabeled? Did you do something special to create this file?

"service network restart" Yes, it is required access. How is /etc/resolv.conf labeled now? # ls -Z /etc/resolv.conf ls -Z /etc/resolv.conf -rw-r--r--. root root system_u:object_r:net_conf_t:s0 /etc/resolv.conf Ok, reopen the bug if this happens again. |
