It's actually working fine writing edited data to the rw sda3 partition
where some folders have been linked to.

I tried that already. I was mounting the entire /home/ingo folder to a
That way I didn't have all files I needed available. All system settings
seemd to be gone.
After getting the data partition to auto mount -rw I made a link to the
.ICEauthority file. Didn't help. Maybe mounting drives comes later in the
upstart order. I should check that out.
