The -e (or --emptytree) option says "treat all dependencies as though |
| 19 |
they need to be (re)installed", so it will reinstall all packages in |
| 20 |
world (or system), and every package that they depend on, and their |
| 21 |
dependencies, all the way down. Note also that in portage-2.1.*, |
| 22 |
"system" is part of "world" (and for portage-2.2, @system will be, by |
| 23 |
default, part of @world, although that will be configurable), so emerge |
| 24 |
- -e world will rebuild every package on your system, except for those |
| 25 |
that would be removed via `emerge --depclean`. |

Just as a suggestion, use "-- " (hyphen-hyphen-space) as a separator |
| 31 |
instead of just "--" (hyphen-hyphen) -- it will cause most clients to |
| 32 |
drop the signature part in replies. |
