Both :> I like the greying of the inst button. This might be fun because
some packages still depend on the obsolete 'elf-x11r6' library. Deity will
immediately mark these for removal and prevent you from installing them
<hmmm, uh oh>
Deity is going to be pretty agressive in ensuring that your system is the
way it should be. Dselect only seemed to care when you performed an
option, Deity knows right from the start if a package is incorrectly
installed and will try to fix it (by removing it or installing something
new).. This might be bad :>

Ah, the controll can ungrey the install box then. Or perhaps we could have
a menu option to force install which will force it into the install or
keep position.
There may be some issues here, it will be a bit before I can tell you what
works nicest..
