Hi Richard & Andreas,

Thanks for replying this mail.

The situation on my side is: if my project include connman and 
networkmanager at the same time, the compile step will fail:
...
Computing transaction...error: Can't install 
xfce4-power-manager-1.4.4-r0.0 at corei7_64: unable to install provider for 
networkmanager:
error:     networkmanager-1.0.4-r0.0 at corei7_64 conflicts with 
connman-1.30-r0.0 at corei7_64
...
The dependence relationship is:
xfce4-power-manager --> networkmanager
packagegroup-self-hosted --> connman

Anyway, the patch is not suitable, Koen Kooi(koen at dominion.thruhere.net) 
has suggested me to fix packagegroup-self-hosted to not specify a 
connection manager.
When i am trying to fix my issue, i was wondering why self-hosted needs 
connman ? if self-hosted really don't need connman, the way provided by 
koen is the best solution for this issue.

The draft patch looks like:
---
--- a/meta/recipes-core/packagegroups/packagegroup-self-hosted.bb
+++ b/meta/recipes-core/packagegroups/packagegroup-self-hosted.bb
@@ -28,8 +28,6 @@ RDEPENDS_packagegroup-self-hosted = "\
      "

  RDEPENDS_packagegroup-self-hosted-host-tools = "\
-    connman \
-    connman-plugin-ethernet \
      dhcp-client \
      e2fsprogs \
      e2fsprogs-e2fsck \

What do you think? is that ok? if so, i will send an official patch for it.

Thanks,
Zhenbo
