          Issue ID: 23962
           Summary: Please move dub and dustmite to separate deb package
           Product: D
           Version: D2
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: installer
          Assignee: nobody@puremagic.com
          Reporter: witold.baryluk+d@gmail.com

dustmite and dub are packages already in Debian and Ubuntu, and I often have them installed together with gdc, ldc2.

When installing dmd deb from dlang website, they cause conflicts, requiring me to uninstall dustmite and dub first.

This is very annoying, and makes testing different versions difficult.

Would be better to split dub and dustmite into own packages, and make them recommend dmd (but not require!).

Finally.

(No idea why so many triggeres are triggered)

As of rdmd and ddemangle I do not have opinions, as they do not cause issues
(yet).
