My understanding is that s6-rc-db lists bundle contents recursively. 
Since default contains boot, the above command will list everything s6 
is going to start. In order to identify *only* those services you have 
added to default yourself, you need to do something like:-

s6-rc-db contents default | tee d.tmp
s6-rc-db contents boot | tee b.tmp
diff b.tmp d.tmp

The diff output should enable you to figure out the appropriate entries 
to make in adminsv/contents.d.

I would just like to add that the new system feels like a huge step 
forward. The old system was operating only on the compiled database, 
whereas the source database now becomes the definitive reference which 
is much easier to understand. I quickly felt comfortable enough to 
disable the compatibility mechanism. Thanks Dudemanguy for doing all the 
heavy lifting.
