This alias is run with coffee every morning on 8 Gentoo installs on this LAN:
alias ud='eix-sync && emerge -aDjNuv @world && dispatch-conf && emerge -a --depclean && revdep-rebuild -i && clear && exit'

So I'd venture to say there never will be such a set (must one create it?).

However, the wife's PC is getting rescued from JFS atm. Having backed up /home
and anything worth saving, booted with SystemRescueCd, and started a fresh
install beginning with changing / and /home to XFS; these configs:

grep PYTHON /etc/portage/make.conf
PYTHON_TARGETS="python2_7"

grep gcc /etc/portage/package.*
/etc/portage/package.accept_keywords:sys-devel/gcc:4.6
/etc/portage/package.use:sys-devel/gcc cxx nptl -gtk

grep udev /etc/portage/package.*
/etc/portage/package.mask:>=sys-fs/udev-181
/etc/portage/package.use:sys-fs/udev rule_generator

necessitated "emerge -aejv @world" from what came with the present tarballs.

So as soon as that's done perhaps "emerge -a @preserved-rebuild" will show
such a set?
