It would by nice if the ebuild names in the output of equery could be directly piped to emerge. The current output (if not a terminal) looks like sys-apps/python-2.2.1-r2. A very useful format would be the form sys-apps/python so "equery belongs /lib/modules | xargs emerge" could update all kernel-dependent packages after kernel upgrade. Currently "equery belongs /lib/modules | sed 's/^/=/' | xargs emerge" does the job, but the drawback is that it doesn't update to newer packages.
I'm undecided on this one: In the meantime "equery belongs /lib/modules | sed 's/-r[0-9].*$//;s/\(^.*\/*\)-.*$/\1/' | xargs emerge" will do what you want.
My concern is that package versions show lots of anomalies ranging from 5b (portmap), alpha5 (libtheora), pre7 (module-init-tools) to v3 (libstdc++), libxml2, ipw2200 and so on. So it is really hard to cut off the version. However I have discovered sys-kernel/module-rebuild in portage which is what I seek. If you wish, mark this report as WONTFIX. But thank you for your precious time.
