I use a web-server, connecting to old (using custom, non-unicode, character set) Oracle database. So I need to customize settings in /etc/env.d/50oracle-instantclient-basic adding line: NLS_LANG=russian_cis.cl8iso8859p5 Today dev-db/oracle-instantclient-basic and dev-db/oracle-instantclient-sqlplus were updated from 10.2.0.3-r1 to 11.2.0.3. Portage updated /etc/env.d/50oracle-instantclient-basic config file to use new client. But during performing these changes database NLS settings were lost. I expect /etc/env.d/50oracle-instantclient-basic config file to be checked and, if user-modified --- not to be silently overwritten, but interactively updated. $ emerge --info Portage 2.1.11.31
