Issue
Description of problem:
After https://fedoraproject.org/wiki/Changes/Sqlite_Rpmdb, rpm changed from Berkeley DB to SQLite. SNMP is using these hardcoded paths to determine where RPM info is, so for example net-snmp-5.9.1-7.el9 [1] is trying to search for /var/lib/rpm/Packages and fails with the following error otherwise
Can't find directory of RPM packages
[1] https://fossies.org/linux/net-snmp/agent/mibgroup/host/data_access/swinst_rpm.c
Version-Release number of selected component (if applicable):
net-snmp-5.9.1-7.el9
Steps to Reproduce:
1. yum install net-snmp net-snmp-utils
2. systemctl enable snmpd
3. systemctl start snmpd
Basically you get a different rpm dir struct, so code should take this into account:
[root@juarezcs9 ~]# ls /var/lib/rpm
rpmdb.sqlite rpmdb.sqlite-shm rpmdb.sqlite-wal
