Description sexiya1178 2025-11-07 13:43:09 UTC
Description of problem:
SELinux is preventing blocking-2 from 'write' accesses on the sock_file io.systemd.DynamicUser.

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

If you believe that blocking-2 should be allowed write access on the io.systemd.DynamicUser sock_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 'blocking-2' --raw | audit2allow -M my-blocking2
# semodule -X 300 -i my-blocking2.pp
