Description of problem:
After lircd start, i launch irw and i get this alert
SELinux is preventing lircd from 'execute' accesses on the file /usr/bin/bash.

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

If vous pensez que lircd devrait être autorisé à accéder execute sur bash file par défaut.
Then vous devriez rapporter ceci en tant qu'anomalie.
Vous pouvez générer un module de stratégie local pour autoriser cet accès.
Do
allow this access for now by executing:
# ausearch -c 'lircd' --raw | audit2allow -M my-lircd
# semodule -X 300 -i my-lircd.pp
