corekeeper 1.6 (amd64 binary) in ubuntu yakkety

 corekeeper enables core files, reports crashes to the sysadmin and
 deletes old core files after 7 days.
 .
 Core file dumping is enabled for all users, to restrict that, please
 remove or edit the config file at /etc/security/limits.d/corekeeper.conf
 .
 On Linux core files are written to private per-userid dirs in /var/crash.
 Linux 3.6 and earlier have an issue that means all core files are written
 to the directory for root. If your system is running Linux 3.6 or earlier
 and is single-user (or you don't care about the privacy of core file names),
 you can avoid this issue by editing /etc/sysctl.d/corekeeper.conf.
 .
 On kFreeBSD files are written to /var/crash, kernel limitations prevent
 core files from being written to private per-userid dirs.
 .
 To fully remove this package it needs to be purged and the system rebooted.
