  - you won't be able to use mercurial repositories unless you install the hg command on your system.
  - you won't be able to use darcs repositories unless you install the darcs command on your system.

This development version of opam requires an update to the layout of /home/opam/.opam from version 2.0 to version 2.2, which can't be reverted.
You may want to back it up before going further.

=> afl-persistent is installed, but since the current OCaml compiler does
   not enable AFL instrumentation by default, most packages will not be
   instrumented and fuzzing with afl-fuzz may not be effective.

   To globally enable AFL instrumentation, create an OCaml switch like:

     opam switch create 5.2.0+afl ocaml-variants.5.2.0+options ocaml-option-afl
# Run eval $(opam env) to update the current shell environment
