Move rc startup scripts from etc/ to sbin/init/

2018-07-28T20:36:23+00:00

This keeps most startup scripts as CONFS per discussion on src-committers from
back during BSDCan.

Allow more services to run in vnet jails

2017-07-08T09:28:31+00:00

After some tests, here are the services that run into a vnet jail:
  - defaultroute
  - dhclient
  - ip6addrctl
  - natd
  - pf
  - pfsync
  - pflog (deamon runs, pflog0 interface usable, but /var/log/pflog not filled)
  - rarpd
  - route6d (do nothing anyway because obsolete)
  - routed (do nothing anyway because obsolete)
  - rtsold
  - static_arp
  - static_ndp

- Use the absolute pathname for ip6addrctl.
- Use "install" instead of "add" to reduce the number of invocations.

Prepare for the removal of set_rcvar() by changing the rcvar=

2012-01-14T02:18:41+00:00

assignments to the literal values it would have returned.

The concept of set_rcvar() was nice in theory, but the forks
it creates are a drag on the startup process, which is especially
noticeable on slower systems, such as embedded ones.

During the discussion on freebsd-rc@ a preference was expressed for
using ${name}_enable instead of the literal values. However the
code portability concept doesn't really apply since there are so
many other places where the literal name has to be searched for
and replaced. Also, using the literal value is also a tiny bit
faster than dereferencing the variables, and every little bit helps.

Split $ipv6_prefer into $ip6addrctl_policy and $ipv6_activate_all_interfaces.

2010-09-13T19:55:40+00:00

The $ip6addrctl_policy is a variable to choose a pre-defined address
selection policy set by ip6addrctl(8).
The keyword "ipv4_prefer" sets IPv4-preferred one described in Section 10.3,
the keyword "ipv6_prefer" sets IPv6-preferred one in Section 2.1 in RFC 3484,
respectively.  When "AUTO" is specified, it attempts to read
/etc/ip6addrctl.conf first.  If it is found, it reads and installs it as
a policy table.  If not, either of the two pre-defined policy tables is
chosen automatically according to $ipv6_activate_all_interfaces.

When $ipv6_activate_all_interfaces=NO, interfaces which have no corresponding
$ifconfig_IF_ipv6 is marked as IFDISABLED for security reason.

The default values are ip6addrctl_policy=AUTO and
ipv6_activate_all_interfaces=NO.
