Ok... After initializing Quicklisp and ASDF, I do:

  (setq asdf:*immutable-systems* (uiop:list-to-hash-set "gendl" ... ))

as well as 

 (asdf/find-system:register-preloaded-system "gendl") 

 ...

with all the known preloaded systems. 

But now if I do

  (ql:quickload :gendl)

I still get this error:

   "Requested system gendl is in the *immutable-systems* set, but not loaded in memory"

Apparently,

   (asdf:system-registered-p "gendl")

is still coming back as NIL.

Is there another step I should be doing?

Using asdf 3.1, you can use *immutable-systems* for that (see its docstring).

There is currently no provision to do it as part of a program-op, so
you may have to do it manually between a load-op and a program-op, or
as part of an image-dump-hook or image-restore-hook, contingent on a
variable that gets reset (the image-dump-hook doesn't work on ECL, and
you must use the ECL-specific epilogue instead; the image-dump-hook
wastes a little bit of time at restart on other platforms).
