This means anyone building a systemd based OS with Yocto/OE Core gets this error for free unless they replace/modify the connman service. I think the default stance should be to ship metadata which is usable without errors for the use case of building an OS to run on target hardware, rather than the metadata being built to support the autobuilder use case first and foremost. Rather than hack the connman.service file to have an ExecPre couldn't the connman-conf recipe provide its own unit which uses the Before= option to ensure it's started before connman? 54682 1 ross.burton 2015-09-25 15:53:11 +0000 Yes, that's an excellent idea. 55286 2 joshuagloe 2015-10-14 09:42:29 +0000 Currently testing the following pair of changes: https://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/commit/?h=joshuagl/connman&id=398ac8777eca62a95b8ea93e8dd4d8c4195ca15f https://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/commit/?h=joshuagl/connman&id=9285c0a1fc970d70ceb306b4d11e9bab472fcbd5 should possibly be squashed... 55287 3 joshuagloe 2015-10-14 10:22:01 +0000 RFC patch series submitted http://lists.openembedded.org/pipermail/openembedded-core/2015-October/111536.html 57153 4 joshuagloe 2015-12-10 09:03:22 +0000 v3 of the series, to address various review comments, has been submitted: http://lists.openembedded.org/pipermail/openembedded-core/2015-December/113933.html 57313 5 joshuagloe 2015-12-16 20:44:18 +0000 Simpler v4 series posted based on feedback from Martin: http://lists.openembedded.org/pipermail/openembedded-core/2015-December/114241.html 58370 6 joshuagloe 2016-02-01 08:01:52 +0000 v5 of canges has landed: http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=79f4495244ceddb197879ae24c33f469285bbff2 http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=d74325e22ed81e49eec63335fd0f4b789f9dfc21 59155 7 daniel.alexandrux.istrate 2016-02-17 15:53:09 +0000 Verified on master: 152914f2983c5d69001de1d46ce99547fa1e75fe Steps: 1. test that qemu machines continue to work as before root@qemux86-64:~# journalctl | grep connman Feb 17 14:41:56 qemux86-64 connmand[422]: Connection Manager version 1.31 Feb 17 14:41:56 qemux86-64 connmand[422]: Adding configuration wired Feb 17 14:41:56 qemux86-64 connmand[422]: Checking loopback interface settings Feb 17 14:41:56 qemux86-64 connmand[422]: System hostname is qemux86-64 Feb 17 14:41:57 qemux86-64 connmand[422]: lo {newlink} index 1 address 00:00:00:00:00:00 mtu 65536 Feb 17 14:41:57 qemux86-64 connmand[422]: lo {newlink} index 1 operstate 0 <UNKNOWN> Feb 17 14:41:57 qemux86-64 connmand[422]: eth0 {create} index 2 type 1 <ETHER> Feb 17 14:41:57 qemux86-64 connmand[422]: eth0 {RX} 32 packets 5573 bytes Feb 17 14:41:57 qemux86-64 connmand[422]: eth0 {TX} 29 packets 4759 bytes Feb 17 14:41:57 qemux86-64 connmand[422]: eth0 {update} flags 69699 <UP,RUNNING,LOWER_UP> Feb 17 14:41:57 qemux86-64 connmand[422]: eth0 {newlink} index 2 address 52:54:00:12:34:56 mtu 1500 Feb 17 14:41:57 qemux86-64 connmand[422]: eth0 {newlink} index 2 operstate 6 <UP> Feb 17 14:41:58 qemux86-64 connmand[422]: Skipping disconnect of carrier, network is connecting.
