Description Mr Beedell, Roke Julian Lockhart 2026-08-23 13:08:01 UTC 
Description of problem:
Observe https://bugzilla.redhat.com/show_bug.cgi?id=2521586#c0.
SELinux is preventing crun from 'unlink' accesses on the fifo_file exec.fifo.

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

If you believe that crun should be allowed unlink access on the exec.fifo fifo_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 'crun' --raw | audit2allow -M my-crun
# semodule -X 300 -i my-crun.pp
