charon.plugins.resolve.file = /etc/resolv.conf
	File where to add DNS server entries if not using resolvconf(8).

charon.plugins.resolve.resolvconf.iface = lo.ipsec
	Interface name/protocol sent to resolvconf(8).

	The interface name and protocol sent to **resolvconf**(8). This has to be a
	valid interface name according to the rules defined by resolvconf.  Also, it
	should have a high priority according to the order defined in
	**interface-order**(5) if relevant on the system.

charon.plugins.resolve.resolvconf.path = /sbin/resolvconf
	Path/command for resolvconf(8).

	Path/command for **resolvconf**(8). The command is executed by a shell, so
	"resolvconf" will work if it's in $PATH of the daemon.

	If not configured, **resolvconf**(8) will be used if found at the default
	location.  Otherwise, the file in _charon.plugins.resolve.file_ will be
	modified directly.
