New Revision: 332663
URL: https://svnweb.freebsd.org/changeset/base/332663
Log:
Move debug.{trace,debugger}_on_panic and kern.panic_reboot_wait_time in
EC2 instances from sysctl.conf to loader.conf; these can all be set as
loader tunables, and setting them in loader.conf gives us the right
behaviour in the event of a kernel panic taking place prior to when
sysctl.conf is processed.
