We could add a systemctl one-shot add-on that would
issue nvme connect-all for each line available in
the discovery.conf file.

Something like:
--
[Unit]
Description=NVMf auto discovery service
After=systemd-modules-load.service network-online.target

[Service]
Type=oneshot
ExecStart=/usr/bin/nvme connect-all
StandardOutput=journal

[Install]
WantedBy=multi-user.target
--

Where discovery.conf would have the relevant parameters
like:
--
--traddr=<traddr1> --trsvcid=<trsvcid1>
--traddr=<traddr2> --trsvcid=<trsvcid2>
--

One thing we may want to have is to make sure
that nvme relevant modules are loaded at boot time
so we may want nvme-cli to either manually load them
or the installation would add them to systemd-modules-load.service
(i.e. add relevant files to /etc/modules-load.d/)

Thoughts?
