[gentoo-user] Automatic package updates

[Kevin Lacquement]

Hello all,

I use Mozilla Thunderbird along with the enigmail plugin.  Whenever I 
update world, it updates Thunderbird, which then tells me to manually 
re-install enigmail.  However, since I generally update world while I'm 
away, I usually forget to re-install enigmail, which means that when I 
want to send a message, my PGP options aren't available.

Is it possible to have portage automatically re-install the enigmail 
plugin (or other similar situations)?
