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.
