Could it be useful an emerge option (for example --halt) to say to shutdown the machine at the end of the emerge process?
just use: emerge something; shutdown -h now :) it works :)
(In reply to comment #1) > just use: > > emerge something; shutdown -h now > > :) it works :) Yes, I know. I already use that statment or something like emerge something; shutdown -h +1 (so I can stop the process without halting the system).
This is request is beyond the scope of features that need to be included in portage itself. You can can trigger anything that you want by using a wrapper script.
