Make it executable:

chmod +x /etc/rc.local

Reboot again, it'll be started on next boot!
I don't think that the `/etc/rc.local` should be part of this procedure... =P
NOTE: Don't need to run `update-initramfs -k all -u`. |

-
So this forces me to have the following `/etc/rc.local` file as a workaround:
-
#!/bin/bash
sleep 6
systemctl start nbd@nbd0
-
Make it executable:
-
chmod +x /etc/rc.local
-
Reboot again, it'll be started on next boot!
I don't think that the `/etc/rc.local` should be part of this procedure... =P
NOTE: Don't need to run `update-initramfs -k all -u`. |
