Description Mai Ling 2022-06-05 14:06:40 UTC
Description of problem:
$ sudo dhclient eth0
/etc/dhcp/dhclient.d/chrony.sh: line 14: /run/chrony-dhcp/eth0.sources: Permission denied

SELinux is preventing dhclient-script from 'create' accesses on the file eth0.sources.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that dhclient-script should be allowed create access on the eth0.sources file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'dhclient-script' --raw | audit2allow -M my-dhclientscript
# semodule -X 300 -i my-dhclientscript.pp
