Cross Rootfs on Git

Nice idea to use put rootfs in Git

1. init git rootfs

   cd /usr/armv4tl-softfloat-linux-gnueabi
   git init
   

2. .gitignore

   var/cache/edb/counter
   var/cache/edb/vdb_blockers.pickle
   var/cache/edb/vdb_metadata.pickle
   var/db/.pkg.portage_lockfile
   var/cache/ldconfig/aux-cache
   

3. adding hack for committing every package to git during emerge, etc/portage/bashrc

   if [[ $EBUILD_PHASE == "clean" ]]; then
           cd ${ROOT} && git add . && git commit -a -m "=${CATEGORY}/${PF}";
   fi
   

4. git usage
   1. man git
   2. GUI: git gui , gitk --all
5. workflows
   1. Now you can easy return back to any git status.
   2. Create branches/tags, allowing you fix errors via ugly hacks, and then return and fix them correctly.
   3. Your...

Cross Rootfs on Git (Method 2)

I use the following to place my $ROOT under git control, it's slightly modified.

1. init git rootfs

   cd /usr/armv4tl-softfloat-linux-gnueabi
   git init
   

2. .gitignore

   var/cache/edb/counter
   var/cache/edb/vdb_blockers.pickle
   var/cache/edb/vdb_metadata.pickle
   var/db/.pkg.portage_lockfile
   var/cache/ldconfig/aux-cache
   tmp/*
   

3. adding hack for committing every package to git during emerge, etc/portage/bashrc (This also executes cross_fix_root and etc-update prior to add/commit)

   if [[ $EBUILD_PHASE == "postinst" ]]; then
   	# This is the cross-fix-root from http://gentoo.mindzoo.de
   	[[ $EMERGE_FROM != binary ]] && cross_fix_root ${CHOST}
   	# This ensures that etc-update is handled before we do git commits
   	ROOT=${ROOT} etc-update
   
   	# This removes the /usr/share/gtk-doc directory
   	rm -rf ${ROOT}/usr/share/gtk-doc
   
   	# This commits newly installed packages to git for tracking
   	cd ${ROOT} && git add . && git commit -a -m "=${CATEGORY}/${PF}, `date`";
   fi
   

The modified version above does the submit only during portinst, executing during clean stage had the add and commit being run twice in most packages, and was resulting in a very large git archive.
