The RootFS from F&S as well as my own RootFS are mount read only. Where can I change this? The bootargs don't set to ro, in etc/fstab it's mount as rw, I also find no setting in buildroot config...
Thanks again for help.

I found out myself. Just removed the "ro" after "nfsroot=/rootfs" in the bootargs. Now I have write access.
The basic idea behind a read-only root filesystem is that you more or less can only switch off the power of the device without having to shutdown first. If you just want to change some configuration, simply call
Then the filesystem remains clean all the time. If you want to write some temporary data, use the /tmp directory which is mounted as a writable RAM disk.
By the way there is also a setting in BuildRoot where you can configure /etc/inittab to mount the root filesystem read-write. Call "make menuconfig" and go to "System configuration". There check "remount root filesystem read-write during boot". This will remove the comment-hashmark in /etc/inittab in front of the line with the remount command.
