 Zhaofeng Li | anyways, it appears that kea is actually right that it does not have the correct permissions
In [29]: print(router.succeed("nsenter -a -t 761 ls -lah /run/kea/"))
router: must succeed: nsenter -a -t 761 ls -lah /run/kea/
router: (finished: must succeed: nsenter -a -t 761 ls -lah /run/kea/, in 0.02 seconds)
total 56K
drwxr-xr-x 2 kea kea 100 Jul 8 23:19 .

 hexa | huh, 755 instead of 750 | 23:23:33 |
| hexa | wild | 23:23:34 |
| Zhaofeng Li | but I don't get how /run/private/kea/dhcp4.sock worked then (the real directory is 755 too), maybe something changed the permission | 23:24:47 |
| hexa | kea's umask is 0077 fwiw | 23:25:28 |
| hexa | maybe weird behavior with DynamicUser and RuntimeDirectoryPreserve? | 23:26:10 |
| hexa | maybe we can find out using an audit rule | 23:27:11 |
| Zhaofeng Li | ok, got distracted | 23:49:42 |
| Zhaofeng Li | change socket-path to /run/private/kea/dhcp4.sock -> permission is correct
then, change kea-ctrl-agent to have ExecStart = "/bin/sh -c \"while true; do sleep 1000; done\""; -> bad permission??
