If you set something with sysctl and want it to be permanent, you
should put it into /etc/sysctl.conf.
For example, I have
kernel.core_pattern = %e-%p-%h.core
in it, so
/proc/sys/kernel/core_pattern
stays as %e-%p-%h.core

The best time to contact me is probably weekends when I have better
connectivity with good luck.
