Everytime


Steps to Reproduce:
1. dnf install pdns pdns-backend-sqlite
2. edit /etc/pdns/pdns.conf to use the sqlite backend
3. setup an sqlite database on /var/lib/pdns/
4. try to start the pdns

Actual results:
after setting all the correct selinux permissions, audit.log shows this:

type=AVC msg=audit(1670783172.019:9025): avc:  denied  { map } for  pid=21704 comm="pdns_server" path="/var/lib/pdns/r3pek.org.sqlite-shm" dev="dm-0" ino=50763508 scontext=system_u:system_r:pdns_t:s0 tcontext=system_u:object_r:pdns_var_lib_t:s0 tclass=file permissive=0


Expected results:
pdns should start normally
