Booting from ssd with no sd-card

Is there an option to add a ssd and to boot directly from ssd with no sd-card?

Not supported as of now on OSMC.

Is it on the road map?

It’s not a priority but Sam has said a few times he’d welcome a PR if someone has time.

OK, thanks for an explanation.

It’s fairly simple to implement, but I haven’t had a chance to do so.

I don’t have an expertise for such thing so I really cannot offer any help.
If you don’t have time for it, I understand.
