The current configuration is not able to start FrankenPHP when mercure
and SELinux are used with a Caddyfile like this:
```Caddyfile
mercure {
transport bolt {
path mercure.db
}
}
```
closes https://github.com/php/frankenphp/issues/2035
Exact error:
```
SELinux is preventing /usr/bin/frankenphp from map access on the file /var/lib/frankenphp/mercure.db.
***** Plugin catchall_boolean (89.3 confidence) suggests ******************
If you want to allow domain to can mmap files
Then you must tell SELinux about this by enabling the 'domain_can_mmap_files' boolean.
Do
setsebool -P domain_can_mmap_files 1
***** Plugin catchall (11.6 confidence) suggests **************************
If you believe that frankenphp should be allowed map access on the mercure.db 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 'frankenphp' --raw | audit2allow -M my-frankenphp
# semodule -X 300 -i my-frankenphp.pp
