[gentoo-user] prune dangers

It seems that prune would break all sorts of software, yes?  In
particular, GNOME and X windows?

Yes, which is why the emerge man page states

       --prune (-P)
              WARNING:  This  action  can remove important packages!  Prune
              looks at each installed package and attempts  to  remove  all
              but  the  most  recently  installed  version.   Prune ignores
              slots, if you require a slot-aware Prune use  emerge --clean.
              Prune  may  inadvertently remove important packages from your
              system.  Use --clean instead  unless  you  really  know  what
              you're doing.

No. In particular the toolchain. GNOME and X work quite happily without
slotted packages in general.

Well.. GNOME doesn't work all that well without glib-2.x and gtk+-2.x. KDE 
wouldn't work particularly well without qt-3.x either and gnupg-1.9.x would 
become pretty broken by removing gnupg-1.4.x... All in all --prune is rarely 
a good idea.. ;)
