Configured nqn

Hi
I think the host nqn file should exist even before the first connection attempt, so
That a management software will be able to first configure the storage to allow connection from this nqn(with ACL).
The rpm spec can run a script during first install to take care of that.

Thanks

Yes, I would say that if nvme-cli is told to use /etc/nvme/hostnqn and the filename is not there for nvme-cli to create the file containing a generated hostnqn per NQN naming standard in the NVMe spec.
