As we working on porting Debian in our embedded platform, we are struggling to write booting script or chroot script from our own linux platform. We booted our linux kernel with minimal filesystem(jffs2) and we doesn't hav e any packages for Xserver or GUI components packages.But everything working fine in chroot debian platform, We need to have a script which has to mount the chroot partition from the usb drive and has to start the xserver or xdm.Can you please suggest me how to run a command after chroot has started in a script.
