Network Security Services (NSS) historically supports 2 different database backends, based on SQLite and dbm. Since Fedora 28, the SQLite backend has been used by default and the dbm backend has been deprecated (NSS Default File Format SQL). This Change is about removing the support for the dbm backend entirely.
Probably the change page should describe more where actually this DB is used and how to see that nothing would break.
After one week, I count the vote as (+0,0,-0). Will wait for additional votes.
Consider me technically -1 until @ignatenkobrain's question on the mailing list and his comment here are addressed.
to comment on this ticket.
