Comment 7 for bug 1257505

> This will probably preclude users from using both unity & gnome-shell in the same install??

no, it's the opposite, it means each desktop can have its version which reduces conflicts (they are co-installable)

> if when you fork g-s-d to u-s-d it creates more significant issues in a Gs session then maybe that should be addressed in some manner

what do you mean? the fork is create to reduce issues in Gs session (e.g allow to drop unity hacks under GNOME and let GNOME use a more recent version than the one that is adapted to Unity)
