Changing the default kernel commandline via menuconfig has no effect

[christianjann]

Changing the default kernel commandline via menuconfig like written in the README (console=ttyAMA0,115200 root=/dev/mmcblk0p2 rw rootwait) has no effect becaus it gets overridden by the imx23_olinuxino_bootlets.patch patch, for example I had to modify this patch to use systemd as default init system:

[chris@thinkpad linux-stable]$ sed -i 's/root=\/dev\/mmcblk0p2/root=\/dev\/mmcblk0p2 init=\/usr\/lib\/systemd\/systemd/g' ../../boot/imx23_olinuxino_bootlets.patch
[chris@thinkpad boot]$ cd imx-bootlets-src-10.05.02/
[chris@thinkpad imx-bootlets-src-10.05.02]$ patch -p1 < ../imx23_olinuxino_bootlets.patch

[chris@thinkpad imx-bootlets-src-10.05.02]$

An older Arch Linux image without systemd will also boot, just with a small error message that /usr/lib/systemd/systemd could not be found and switching back to default init.
