[Test Plan] * Install new linux-base and initramfs-tools * create /etc/kernel-img.conf with do_symlinks = yes do_bootloader = no do_initrd = yes link_in_boot = yes * Install one kernel flavour, check that symlinks in /boot have sane targets * Install another kernel, check that symlinks in /boot/ have sane targets * create a selfbuilt kernel and install it by calling installkernel (you can download kernel debs from kernel-ppa, and unpack them to pretend one has self built it). and check that symlinks in /boot have sane targets. * Purge all kernel, and remove symlinks in /boot * Update /etc/kernel-img.conf to do_symlinks = yes do_bootloader = no do_initrd = yes link_in_boot = no * Install one kernel flavour, check that symlinks in / have sane targets * Install another kernel, check that symlinks in / have sane targets * create a selfbuilt kernel and install it by calling installkernel (you can download kernel debs from kernel-ppa, and unpack them to pretend one has self built it) * remove all kernels, purge initramfs-tools, clean up symlinks in / and /boot * repeat all of the above, without having initramfs-tools installed. I.e. install kernels _without_ recommneds. [Where problems could occur] * The rewritten postinst.d script now simply mostly calls linux- update-links like the normal linux-image postinst script does. One has to make sure that .deb installations of kernels happens correctly and that installkernel way of installing kernels happens correctly. Under different kernel-img.conf settings. The previous incarnations of fixing this and related issues did not account for the above cases and codepaths.
