Description of problem:
The certutil tool shipped in Fedora 29 package nss-tools creates a certificate database in different files than before. Qnetd does not expect that which results in qnetd cannot start after creating its certificate database. There may be other issues as well in both corosync-qnetd and corosync-qdevice as "cert8.db" is hard-coded in corosync-qnetd-certutil.

Version-Release number of selected component (if applicable):
[root@fed28-node3:~]# rpm -q corosync-qnetd
corosync-qnetd-2.91.0-1.fc29.x86_64
[root@fed28-node3:~]# rpm -q corosync-qdevice
corosync-qdevice-2.91.0-1.fc29.x86_64
[root@fed28-node3:~]# rpm -q nss-tools
nss-tools-3.37.3-3.fc29.x86_64


How reproducible:
always, easily


Actual results:

Expected results:
corosync-qnetd-certutil should be able to create a certificate database which qnetd can start with.


Additional info:
It works fine with Fedora 27:
