Just now I've used user_patch feature to check upsteam's patch on bug #421343 At the same time I've checked upstream's patches for another bug https://bugzilla.xfce.org/show_bug.cgi?id=9036 For all iterations package version wasn't changed: $ eix -Ie xfce-extra/xfce4-eyes-plugin [I] xfce-extra/xfce4-eyes-plugin Available versions: 4.4.1-r1 {{debug}} Installed versions: 4.4.1-r1(10:01:33 04.03.2013)(-debug) Homepage: http://goodies.xfce.org/projects/panel-plugins/xfce4-eyes-plugin Description: A panel plug-in which adds classic eyes to your every step It looks bad. To my mind, user_patch on success should also mark patched packages (for example by adding "up" --- suffix meaning applying on source tree user-patches and N --- count of applyed patches). In my case of xfce-extra/xfce4-eyes-plugin ot means that entirely portage tree built version should like as qouted. First iteration of check (two user patches applied: update config patch and initial implementation for upstream bug 9036): Installed versions: 4.4.1-r1-up2(10:01:33 04.03.2013)(-debug) Second iteration of check (three user patches applied: fix for initial implementation added): Installed versions: 4.4.1-r1-up3(10:01:33 04.03.2013)(-debug) $ einfo Portage 2.1.11.52

If classified as feature request for future EAPI, it will be good, if possible, to mark not only user_patch'ed installed packages, but also, depending on present /etc/portage/patches/<CATEGORY>/<PF|P|PN>[:SLOT]/ directories see user_patch mark (for example 'up' suffix) on Available packages, targeted for applying user_patch.
I would suggest to not encode such information in the version but only in a separate file in the /var/db/pkg database - this is the place where such information belongs. In this case the extension might go without EAPI bump since AFAIK the information stored in /var/db/pkg is not limited by pms.
I'm closing this as dup of the user patch applying function request. We can discuss how the function works and what are the results there :). *** This bug has been marked as a duplicate of bug 475288 ***
