Ubuntu(raspbian) /etc/network/interfaces 配置里面 wpa-roam 是什么意思

[ceclinux]

折腾raspberrypi的时候刷了raspbian，对里面的/etc/network/interfaces里面的配置感到好奇。

我是这么配置静态IP的

auto lo
iface lo inet loopback
iface eth0 inet dhcp
auto wlan0
allow-hotplug wlan0
iface wlan0 inet manual
    wpa-roam /home/pi/wlan0.conf
iface default inet static
    address 192.168.1.7
    gateway 192.168.1.1
    netmask 255.255.255.0
    network 192.168.1.0
    broadcast 192.168.1.255

查了man interfaces和debian wiki里面的内容，找不到相应的条目，求教

@Septembers 感谢，不过没有人找的到具体的文档。I assume that, wpa-conf is the static configuration which not needed for roaming through network interfaces. I couldn't find any relevant and detailed document for this.
