The current Portage Tree is over several hundret megabytes in size, so syncing, especially with a low-speed internet connections takes forever.
A solution would be, to reduce your Portage Tree. With rsync_excludes you cann tell portage to only copy ebuilds for packages which are installed on your system. So, here's what we do.Install Gentoolkit
The gentoolkit package is a prerequisite. Install it.
emerge gentoolkit -av
Now we have to edit our /etc/make.conf file. We're loocking for PORTAGE_RSYNC_EXTRA_OPTS and modify it:
# PORTAGE_RSYNC_EXTRA_OPTS can be used to feed additional options to the rsync # command used by `emerge --sync`. This will not change the default options # which are set by PORTAGE_RSYNC_OPTS (don't change those unless you know # exactly what you're doing). PORTAGE_RSYNC_EXTRA_OPTS="--exclude-from=/etc/portage/rsync_excludes --delete-excluded --delete-before"
Save and close your editorDamnSmallPortage Script
The next step is to create a adapted version of our /etc/portage/rsync_excludes. To do this, we use our little script:

sh ./damnsmallportage.shand copy the created rsync_excludes to /etc/portage
mv rsync_excludes /etc/portage/Reduce Portage Tree
Only thing left is syncing
emerge --syncIn this step, all unnecessary ebuilds are going to be erased. After that, our tree is extremly small
du -sh /usr/portage/ 39M /usr/portage/Known problems
If you wan't to emerge a package, which is not in your small Portage tree, e.g. nano, you'll get this error:
emerge nano Calculating dependencies emerge: there are no ebuilds to satisfy "nano".What we have todo, is to edit /etc/portage/rsync_excludes and add the missing package at the very top of the file.
+ app-editors/nano + metadata/cache/app-editors/nanoA list of all current ebuilds in the official tree can be found on http://www.gentoo-portage.com/
# emerge nano -v These are the packages that would be merged, in order: Calculating dependencies... done! [ebuild R ] app-editors/nano-1.3.11-r2 Total size of downloads: 1,145 kBIf for some reason you need the complete tree an your system, just comment out the PORTAGE_RSYNC_EXTRA_OPTS part in /etc/make.conf:
#PORTAGE_RSYNC_EXTRA_OPTS="--exclude-from=/etc/portage/rsync_excludesan re-run emerge --sync
