I couldn't tell you who I ripped this off of but my cron routine is:

ionice -n 7 nice -n 20 emerge --sync              (alternatively
emerge-webrsync -k - preferred actually if you're using rsync)
ionice -n 7 nice -n 20 layman -S
emerge -puDv --changed-use world | col -bx | mutt -s "world update"
root@localhost
eix-update

Then I do this:
#!/bin/sh

LIST=$(mktemp);

emerge -puD --changed-use --color=n --columns --quiet=y --with-bdeps=n
world | awk '{print $2}' > ${LIST};

for PACKAGE in $(cat ${LIST});
do
  printf "Building binary package for ${PACKAGE}... "
  emerge -uN --quiet-build --quiet=y --buildpkgonly ${PACKAGE};
  if [[ $? -eq 0 ]];
  then
    echo "ok";
  else
    echo "failed";
  fi
done

That isn't optimally efficient, but works reasonably well.

The result is that the next morning I have an email containing a list
of the stuff to be merged, and a set of binary packages for most of it
(deps of modified packages cannot be pre-built in this way of course).
Then I just run an "emerge -uDNkv" world to install all of it, often
in minutes.

The script could be optimized - if libreoffice and chromium are on the
list and I don't install them for a few days, suffice it to say that
the heater won't be running as much those nights.
