kernel-image.git
Наброски mike@ по части сборки kernel-image из git-репозитория (точнее, gear-).
Локально в /pub/git/linux-2.6.27.y автоматически синхронизируется master с git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.27.y.git и рядом поддерживаются бранчи с приложенными базовыми патчами.
NB: вместо fetch бранчей стоило бы узнать пораньше про git-remote(1) и обновлять не путём fetch бранча, а pull тега. (thx lakostis@)

При обновлении делаем rebase всех topic branch'ей на kernel-source и затем merge -s ours в основной бранч (в данном разе fix-core-getline стал уже неактуален -- merged upstream):

PS: разглядывая updatemodules, дошло, что бранч master стоило называть kernel-image-tmc-tc. Поправил.
Соответственно модули:
cd ~/build-modules
mv out/taglist{,-}
updatemodules -k tmc-tc
buildmodules --target=i586 --hsh-options='--apt-conf=/etc/apt/apt.conf-i586' --hsh-workdir=$TMP/tmpfs -k tmc-tc
# если порядок, пушим
cd modules && git push --all && git push --tags && cd -
for tag in $(cat out/taglist); do ssh git.alt task add repo packages/kernel-modules.git $tag; done
