What I found was that if roxterm-gtk3 is installed, but not roxterm (the old
virtual package), dist-upgrade doesn't install the new roxterm package. I
was expecting the 'Replaces: roxterm-gtk3' in the new roxterm to make that
happen. 'apt-get install roxterm' does remove roxterm-common and
roxterm-gtk3, replacing them with roxterm-data and roxterm, which is good.
Should I just leave it at that, or is there something I can and should do to
persuade dist-upgrade to automatically replace roxterm-gtk3 with the new
roxterm? How would I do that? 'Provides: roxterm-gtk3' perhaps?
Make roxterm-gtk3 a dummy transitional package (i.e. Section: oldlibs,
Priority: extra), and have it depend on roxterm (and keep the dummy
package around for at least one release to facilitate upgrades).
