Package: ejabberd Version: 17.08-3 Severity: wishlist Dear maintainer team,
please consider to make ERL_OPTIONS configurable with debconf. Specifically, this would allow to set ERL_OPTIONS="-env ERL_CRASH_DUMP_BYTES 0" to prevent Erlang crash dumps from accumulating on a system. The setting is in /etc/ejabberd/ejabberdctl.cfg, which symlinks to /etc/default/ejabberd, which is a Debian conffile. Adding the option to debconf would help FreedomBox (a Debian pure blend), where we try to obviate the need of a specialized admin. That's why we refrain from editing conffiles directly, as it would leave unattended-upgrades unable to upgrade ejabberd without manual intervention. Disabling crash dumps is desirable because their unbounded accumulation can take down the entire system (which actually happens in the wild): If ejabberd keeps crashing and being continually restarted via systemd, the dump file accumulation might fill the entire partition, potentially rendering the system unusable, at a rate of about 4 GiB per day. Such a scenario is particularly severe for our use-case of single-board computers, and essentially absent admins. Thank you for your time and consideration; keep up the great work. Johannes Keyser
