It does, but you need SSH access. Why folks disable all SSH access is a total freaking mystery to me. Someone did that a couple weeks ago here on a device that had NO display port, and they coudn't get into the web panel. Well at that point there's absolutely no way to trouble shoot and nothing you can do but reinstall.
If you're managing this remotely via reverse-proxy of the webUI, just reverse proxy the wetty plugin, and bam.. you have secure command line access (just make sure you're using good passwords, etc.). If you're using a VPN, there's absolutely no reason to disable SSH as it's only available on the local network unless you do something like open up port 22, which isn't necessary
Sorry this happened, but it's really your own fault. If the person in Hawaii can't plugin a display and keyboard and run omv-firstaid for you... you'll have to put OMV on a new sdcard and ship it to them to install, and then start over.
