Description adamkis750alt 2025-12-01 14:44:03 UTC
Description of problem:
SELinux just randomly sent me an AVC denial alert. From what I've heard, bwrap is a built-in program, so it shouldn't be blocked.
SELinux is preventing bwrap from 'mounton' accesses on the directory /tmp.

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

If you believe that bwrap should be allowed mounton access on the tmp directory 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 'bwrap' --raw | audit2allow -M my-bwrap
# semodule -X 300 -i my-bwrap.pp
