Subject: Bug #243220 - Show messages in emerge.log when old versions are uninstalled
X-Git-Tag: v2.1.6.12~151
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=84f58cb7f4f9985da35130bea1243c8da3ff4c04;p=portage.git

Bug #243220 - Show messages in emerge.log when old versions are uninstalled
for AUTOCLEAN. This reverts behavior so that messages which used to be
generated prior to portage-2.1.5.x (when AUTOCLEAN was moved from emerge to
dblink.treewalk()) are generated once again. (trunk r13241)
