9 It's not slotted, so that answers your first question.
11 Also, gnome is a *bunch* of executables and libraries, so it's not as
12 simple as renameing "gnome-session" to "gnome-session3".
14 To answer the first, if you have two or more of the same package, say
15 "foo", then slots tell portage that more than one version of "foo" may
16 be installed if they are in different slots. For example, python-2.7.*
17 packages are in slot "2.7" and python-3.2* packages are in slot "3.2" so
18 python-2.7.2-r2 and python-3.2-r2 may be installed simultaneously.
19 However, ex., 2.7.1-r2 and 2.7.2-r2 may not (because they are in both
20 slot) "2.7".
22 Similarly gnome-2* and gnome-3* (from the "gnome" overlay) are both in
23 slot "2.0".
25 The reason why GNOME 3 is in slot "2.0" is that it cannot be installed
26 alongside GNOME 2, so no use in bumping the slot #.
