Putting aside that you cannot put that aside as that would turn openHAB unreachable for the majority of people, the answer is a simple No.
(I’m tired of this discussion and won’t join it again, read up here, nothing has changed about that)
No. “People”'s preference is to have a cheap, easy to use turnkey system: the no-frills SD based RPi.
Anything that makes it more complicated and more expensive turns them down.
While rarely people like yourself keep asking for this so far noone has been willing to put the required amount of work into implementing this. SSDs are simply just not implemented/validated to work with openHABian. Note however “implementing” and “validating” doesn’t mean to setup a single instance. It means to ensure, i.e. test and validate that it works with each and every RPi model and other peripheral you want to support, in every combination of hardware openHABian has been supporting, and in combination with every software feature it has been supporting, too (think of mirroring, backup & restore etc).
Evolve your manual installation procedure into a fully parametrized scripted one and validate that it works reliably with all possible SSDs and combinations of HW and SW, turn it into a PR and I’ll happily add it to openHABian provided it that it is in accordance with the coding guidelines.
Oh, and don’t forget to submit vacation to your employer to have the time available it’ll take to help all those people that will be having questions about and problems with using this including all the stuff that’ll come up on upgrades.
My personal decision is I’m not willing to spend any of my personal scarce spare time to help a tiny minority of people accomplish something only they want but noone really needs.
(BTW you two are the only ones I’m aware of that asked for it since that linked thread, i.e. end of '22)
But there is no such “decision” of mine on behalf of openHABian that it cannot become supported.
Just I will not be supporting it. But feel free to join development and make OSS happen.
Or pick and work on any other of the open issues.
So anyone to think along the same lines as Oliver, I’m looking forward to receiving your PRs.
However, if you’re not truely willing to provide any such contribution, please refrain from asking for or promoting it as a presumably good idea. Thank you.
