开发板buildroot dbus各种报错

S10mdev：

Starting mdev...
modprobe: can't change directory to '/lib/modules': No such file or directory

先创建各种文件夹

modprobe: can't open 'modules.dep': No such file or directory

然后再busybox里面添加depmod

/etc/init.d/S30dbus start

Starting system message bus: Failed to start message bus: Could not get UID and GID for username "dbus"
done

再执行depmod
# ./etc/init.d/S10mdev start
Starting mdev...
nl80211: Could not re-add multicast membership for vendor events: -2 (No such file or directory)

wpa_supplicant -B -i wlan0 -c ${env_wifi_wpa_supplicant_conf} -D nl80211&

S30dbus：

etc/passwd添加

dbus:x:1000:1000:DBus messagebus user:/var/run/dbus:/bin/false
