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

Continue? [y/n] y
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.
