We run the ping test as soon as we reach the login prompt.
But sometimes (seen in sato systemd) we end up with link down/link up stuff like:
qemux86-64 login: IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
e1000: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX
IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
The logic behind ping -w 30 -c 1 was to wait at most 30 seconds
for at least one reply, but there is a catch: reply doesn't seems
to be echo reply but any reply (non-reply means loss not network error)
ping's man page:
-w deadline
Specify a timeout, in seconds, before ping exits regardless of
how many packets have been sent or received. In this case ping
does not stop after count packet are sent, it waits either for
deadline expire or until count probes are answered or for some
error notification from network.
Just when the link up/link down happens ping returns:
From 192.168.7.1 icmp_seq=1 Destination Host Unreachable
--- 192.168.7.2 ping statistics ---
1 packets transmitted, 0 received, +1 errors, 100% packet loss, time 0ms
and exits sooner than the 30 seconds timeout.
This patch should do what was originally intended (wait at most
30 seconds for at least one reply).

Poky
====
Poky is an integration of various components to form a complete prepackaged
build system and development environment. It features support for building
customised embedded device style images. There are reference demo images
featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
cross-architecture application development using QEMU emulation and a
standalone toolchain and SDK with IDE integration.
Additional information on the specifics of hardware that Poky supports
is available in README.hardware. Further hardware support can easily be added
in the form of layers which extend the systems capabilities in a modular way.
As an integration layer Poky consists of several upstream projects such as
BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information
e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
The Yocto Project has extensive documentation about the system including a
reference manual which can be found at:
http://yoctoproject.org/documentation
OpenEmbedded-Core is a layer containing the core metadata for current versions
of OpenEmbedded. It is distro-less (can build a functional image with
DISTRO = "") and contains only emulated machine support.
For information about OpenEmbedded, see the OpenEmbedded website:
http://www.openembedded.org/
Where to Send Patches
=====================
As Poky is an integration repository, patches against the various components
should be sent to their respective upstreams.
bitbake:
bitbake-devel@lists.openembedded.org
meta-yocto:
poky@yoctoproject.org
Most everything else should be sent to the OpenEmbedded Core mailing list. If
in doubt, check the oe-core git repository for the content you intend to modify.
Before sending, be sure the patches apply cleanly to the current oe-core git
repository.
openembedded-core@lists.openembedded.org
Note: The scripts directory should be treated with extra care as it is a mix
of oe-core and poky-specific files.
