Well, when I run into this (my old netbook needs over 15 minutes for the
dependency calculations of a deep world update), I do -avuD world. Once the
output is shown, portage will wait for me to answer 'yes'.
Then I go to another terminal where I run emerge -f with the -O option,
because now I know which packages to fetch, thus eliminating the need for a
second dependency calculation. If the list of packages is small, I just type
the names by hand. If the list is larger, I usually prepare a list in vim
that I can paste to the emerge command.
Say you have output from emerge like so (my situation right now):
...
[ebuild U ] media-fonts/dejavu-2.34 [2.33] USE="X -fontforge" 4.597 KiB
[ebuild U ] dev-libs/tinyxml2-2.2.0:0/2 [1.0.9_p20121123:0/0]
USE="-static-libs {-test}" 445 KiB
[ebuild rR ] kde-base/libkexiv2-4.14.3:4/4.14 USE="xmp (-aqua) -debug" 0
KiB
...
Copy-paste that into a file 'emerge.out'. If you run screen/tmux, that’s
easily done even on a mouse-less terminal. Then use the following
sed-oneliner on it which I just conjured up:
sed -e '/ 0 KiB$/d' -e 's/.\{17\}/=/' -e 's/ .*//'
It first removes all lines ending in " 0 KiB" (meaning no download
necessary) and then removes everything around the package name and version,
converting
[ebuild U ] media-fonts/dejavu-2.34 [2.33] USE="X -fontforge" 4.597 KiB
into
=media-fonts/dejavu-2.34
Finally, feed that to emerge -fO:
emerge -fO $(sed -e '/ 0 KiB$/d' -e 's/.\{17\}/=/' -e 's/ .*//' < emerge.out)
