# PROVIDE: dhclient
Support code for the OpenBSD dhclient. This significantly changes the way interfaces are configured. Some key points: - At startup, all interfaces are configured through /etc/rc.d/netif. - ifconfig_<if> variables my now mix real ifconfig commands the with DHCP and WPA directives. For example, this allows media configuration prior to running dhclient. - /etc/rc.d/dhclient is not run at startup except by netif to start dhclient on specific interfaces. - /etc/pccard_ether calls "/etc/rc.d/netif start <if>" to do most of it's work. - /etc/pccard_ether no longer takes additional arguments to pass to ifconfig. Instead, ifconfig_<if> variables are now honored in favor of pccard_ifconfig when available. - /etc/pccard_ether will only run on interfaces specified in removable_interfaces, even if pccard_ifconfig is set.

- Add descriptions to most of the rc scripts. Those are mostly taken from their daemon's manpage and probably improved. - Consistently use "filesystem" not "file system". Approved by: bapt, brueffer Differential Revision: D452

desc="Dynamic Host Configuration Protocol (DHCP) client"
Luke Mewburn has indicated that they (NetBSD) are not interested in keeping the scripts under rc.d in sync with us. So, remove NetBSD specific stuff (which made our scripts more complicated than necessary). The NetBSD ident string will be left intact, both for history and also incase we wish to pull in future versions.

rc.d: document 'quiet' prefix and fix dhclient/devd interaction Document the current semantics of the 'quiet' command prefix in the rc.subr(8). Fix dhclient rc.d script: it should not call err() for non-DHCP-enabled interface when it is called from devd, because the latter just blindly calls 'service dhclient quietstart' on each "link up" event. Since the 'quietstart' will silence the message "Cannot 'start' <foo>. Set <foo>_enable to YES in /etc/rc.conf or use 'onestart' instead of 'start'." and running dhclient on the non-DHCP-enabled interface is the same thing as running the service <foo> without <foo>_enable set, such modification is in sync with the current semantics of the 'quiet' prefix.

load_rc_config network
Implement individual operations on static and dhcp interfaces. Previously network interfaces could only be turned on and off as a group (all static interfaces or all dhcp interfaces). When used to start the interface a 'long form' ifconfig output is used to show the status of the interface, but when stopping an interface the script will simply output the name of the interface. This is simply my personal preference. Hopefully as this functionality matures we can stabilize on a prefered form of output for these scripts. A stop command to the dhclient script now explicitly releases the dhcp lease. Behaviour at system shutdown; however, is unchanged since dhclient is not, by default, run at that time. The client will not release its lease at shutdown.
