Improve backwards compatability and leave securelevel the old way. 2000-04-10 01:00:04 +04:00			`#!/sbin/sysctl -f`

The file /etc/sysctl.conf is now run with sysctl -f at boot time. This replaces the previous /etc/rc.d/sysctl. Also, the variables are now set earlier, between ipf/ipnat and the network coming up. The rc.conf defcorename and securelevel variables are no more. You can set them directly in sysctl.conf now. 2000-04-09 03:02:53 +04:00			`#`

Switch the default value (if no options DDB_ONPANIC is defined) for ddb.onpanic to 1, change it back to 0 in sysctl.conf and make sure postinstall installs this setting. This avoids us trying to dump while booting from install CD, but keeps the default the same once we are far enough through /etc/rc.d. Failing earlier is unlikely to be recovered by an automatic reboot. OK: core. 2009-03-12 02:22:57 +03:00			`# Default on panic: dump core and reboot. See savecore(8) for information.`

Use the new ?= operator to set the on_panic value for the optional ddb hierachie. 2009-04-01 20:20:55 +04:00			`ddb.onpanic?=0`

Death to nfsiod! It is replaced by kernel threads that do the same thing. The number of kernel threads used is set with the vfs.nfs.iothreads sysctl. 2000-04-16 01:14:48 +04:00			`# Default core name template:`
