I got this message after an update:

 * Messages for package sys-apps/util-linux-2.24.1-r2:

 * The mesg/wall/write tools have been disabled due to USE=-tty-helpers.


I understand that wall has been moved from sys-apps/sysvinit to sys-apps/util-
linux, but I am not sure why USE=-tty-helpers is disabled as a default.  I 
couldn't find anything mentioning this in gentoo-dev, but this could just be 
my poor searching skills.  Does anyone know?
