start-stop-daemon is installed as part of the base system, before lb_chroot_dpkg runs. flash-kernel is not, and if it's going to be installed then it will be installed after flash-kernel. This means that the requirements are different. I'm not sure whether it's possible for dpkg to be upgraded in the context of a live-build run. If it is, then start-stop-daemon needs to be handled using dpkg-divert; otherwise, it isn't necessary. > Additionally, I see you symlink /bin/true from outside the chroot to > act as a dummy /usr/sbin/flash-kernel. No, symlinks don't work that way. The result of 'ln -s /bin/true chroot/usr/sbin/flash-kernel' is that chroot/usr/sbin/flash-kernel becomes a symlink inode with the text '/bin/true', which is resolved at the point when it's opened, not before. If you open /usr/sbin/flash-kernel inside the chroot, then you'll get /bin/true inside the chroot. It's not possible to create a symlink that will result in the contents of a file outside the chroot when opened inside the chroot. > This is problematic if the (E)ABI between the host system and chroot > system are incompatible (eg. armel host and armhf chroot) as the > binary will not be executable and thus most likely cause the build to > fail if flash-kernel is called.
