# corekeeper dump adds privacy for multi-user systems.
# Only root can see what software crashed for other users.
# Non-root users can see that something crashed, no way to fix that.
# It requires Linux 3.7-rc1, see v3.6-6800-g12a2b4b in linux.git for info.
# If you use it with an earlier kernel then only root can access core dumps.
# If you don't want to use it, comment core_pattern below and uncomment this:
