| 4 | Subject: Squelch locale warnings in Debian package maintainer scripts |
| 5 | |
| 6 | Bug-Debian: http://bugs.debian.org/508764 |
| 7 | |
| 8 | The system locales are rather frequently out of sync with the C library |
| 9 | during package upgrades, causing a huge amount of useless Perl locale |
| 10 | warnings. Squelch them when running package maintainer scripts, detected |
| 11 | by the DPKG_RUNNING_VERSION environment variable. |
| 12 | |
| 13 | Any real locale problem will show up after the system upgrade too, and |
| 14 | the warning will be triggered normally again at that point. |
