OK!??

After non-booting and correction of (lot of) typos I switched between stock and openmode kernel.
Still it did not work, so I double-checked and found that I could not delete (rm) the links from stock/closed kernel, even with devel-su and develsh. So I checked those links and I created them as root under openmode. ! ?
OK, nevertheless created a new account for SIP (working under stock kernel).
Then booted to open kernel and expected my accounts to ask for passwords. Guess what?
Right. There was nothing asking me. Everything was right. All my e-mail accounts worked directly. Of course the SIP could not connect.
Then created another mail account under open mode and rebootedL no password was asked, so everything fine.
What should I say?
No need for my little hack (which would need more testing) and no need to reflash (Jonni's proposed method). But maybe I will go for this once again . Maybe (right now no need anymore).

P.S.: I do not understand it and I feel tricked/cheated/verarscht ...
