At this time systemd journald uses the /run tmpfs to store logs by default systemd uses 15% of available space [1] of the /run partition, when the space runs out journald starts to vaccum/store the logs into /var/log [1]. It causes two problems one of them is timeout dev-ttySN.device's when enable debug and use journal as systemd.log_target [2] the other is related to don't find syslog entries into the journal log [3]. This problems are now more evident because i recently enabled the systemd debug option in testimage [4]. One area of improvement will be add support in systemd journald to read these parameters from the kernel cmdline like systemd.log_target, if the support exists we could add that parameter at level of testimage.

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 = "nodistro") 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 (built using a tool called combo-layer),
patches against the various components should be sent to their respective
upstreams:
bitbake:
Git repository: http://git.openembedded.org/bitbake/
Mailing list: bitbake-devel@lists.openembedded.org
documentation:
Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
Mailing list: yocto@yoctoproject.org
meta-poky, meta-yocto-bsp:
Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto(-bsp)
Mailing list: poky@yoctoproject.org
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.
Git repository: http://git.openembedded.org/openembedded-core/
Mailing list: 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.
