15 This fails with portage >= 2.1.1 (iirc). Before that --emptytree caused all
16 packages to show up as New - i.e. as not installed. With portage >= 2.1.1
17 they'll show as installed i.e. U(pdate) or R(eplace)... `man emerge` for
18 details. And that's not the only thing that's flawed with that sed. It gets
19 the version that would be installed rather that what is installed...

21 This should work:
22
23 # cd /var/db/pkg && \
24 emerge -peq system | sed -n 's|^\[ebuild[^]]*\] \([^ $]\+\).*$|\1|p' | \
25 sed -r 's/-[^-]+(-r[0-9]+)*$//' | while read pkg; do
26 for p in "${pkg}-"*; do
27 quickpkg "=$p";
28 done;
29 done

42 It's reinstall targets and all dependencies (indirect as well as direct). It
43 used to be pretend nothing is installed but it doesn't really do that anymore
44 (would result in stupid circular deps aborts even though the deps were
45 installed)...
