The added complexity comes from the fact that reverse dependencies will
have to be modified to depend on "octave | octave-cli" (or "octave |
octave-gui", depending on the splitting scheme that we choose). This can
be achieved first by making the relevant change to octave-pkg-dev, then
binNMUing the arch:any 'Forge packages, and making sourceful uploads for
the arch:all 'Forge packages. The binNMUs will be needed anyways for the
liboctave1->liboctave2 transitions, but the rest is a net extra cost
(and we have several dozens of arch:all packages that will need
sourceful uploads).
An alternative may be to add "Provides: octave" in the new octave-cli
(or octave-gui). I am not sure however if it is ok to provide a name
that is also the name of a real package.
Note that if we decide to do the split, I would rather create a new
octave-cli package and have "octave" ship the GUI version. This is
because starting with Octave 4.0, the GUI will be the default, so it
makes more sense to have it in "octave".
Also note that in what I pushed to git, I did not (yet?) split the
package. So the octave package ships 3 binaries: octave, octave-gui and
octave-cli.
