[Gumstix-users] Frustrated findings from running Yocto/Denzil on Gumstix/Overo

[Arne L. <Arn...@si...>]

Hi again,

Findings from today after running the Yocto/Denzil build from this morning, using:
PREFERRED_PROVIDER_udev = "udev"
in conf/local.conf

System:
Yocto (Built by Poky 7.0.2) 1.2.2 overo ttyO2

Linux:
Linux overo 3.2.0 #1 PREEMPT Thu Jan 17 12:54:54 CET 2013 armv7l GNU/Linux

root@overo:~# systemd-analyze                                                   
Startup finished in 3571ms (kernel) + 33319ms (userspace) = 36891ms

My goal is to make a much faster userspace boot-time, 33 seconds it 20 too much. I see reports on 8 seconds (EarthStorm/Tobi).
And, hopefully, to make the system run on fewer milliamperes, currently, I am somewhere between 240-300 mA...

So, how to I avoid starting not needed services/devices, e.g., bluetooth/rfcomm/hci services? I have spent some time learning about systemd, which I now understand has replaced sysinitv. But I cannot understand which servcies is started, from where... And,  it seems that my buildsystem is a hybrid systemd/sysinitv, and it also reports about LSB: E.g., 
* /etc/inittab is still there, but is it in use?
* /etc/init.d/ is populated with some files, but are they used?
* /etc/rcX.d directories still exist, and they are populated with some symbolic links
* my system uses BusyBox, why?
* opkg seems not to be able to install anything
* many systemd tools I find in the internet literature is not there

The frustrating thing is that the Linux/Gumstix universe is now moving so fast that most of the online literature is not valid anymore. And I cannot seem to find any valid documentation for the build I have. And, I know that the bleeding edge is at Linux 3.6, so...

Hopefully, somebody has some pointers that I do not find via Google..??

Best regards

Arne
