Initramfs problems with the new kernel-package, and a solution

I’ve been using Manoj’s new kernel-package for some weeks now, and used it to compile two kernels (a reconfigured and the new Both times I’ve had trouble with initrd.

As the documentation says, kernel-package kernel packages no longer do their own initramfs generation. One must copy the example scripts at /usr/share/doc/kernel-package/examples/etc.kernel/postinst.d/initramfs and /usr/share/doc/kernel-package/examples/etc.kernel/postrm.d/initramfs to the appropriate subdirectories of /etc/kernel/. However, this is not enough.

My /etc/kernel-img.conf file had the usual posthook and prehook lines calling update-grub. Unfortunately, those hooks are called before the postinst.d hooks, and so update-grub never saw my initramfs images.

Fix? I removed those lines from /etc/kernel-img.conf and created a very simple postinst.d and postrm.d script:



I call the script zzz-grub-local, to ensure that it runs last.

  1. kernel-package (12.008) unstable; urgency=low

    * [55b39b3]: Move invocation of postinst hook scripts after
    /etc/kernel/*.d/* scripts A lot of people have update-grub in their
    /etc/kernel-img.conf postint_hook setting. If that is called early,
    the initramfs invocation in /etc/kernel/postinst.d/initramfs has not
    yet happened, so the update grub script does not notice the
    initramfs, making the system unbootable. Yes, the update grub cant
    be moved into /etc/kernel/postinst.d/ too, but this is friendlier.
    Bug fix: “postinst hook script (update-grub) ran before
    /etc/kernel/postinst.d/initramfs.”, thanks to Jean-Luc Coulon (f5ibh)
    (Closes: #523931).

    Did this not work for you?

  2. Well, for some reason my aptitude never upgraded kernel-package beyond 12.002. I never looked at what the vesrion is in unstable, since I assumed my apt would have upgraded it if so. It turns out I had kernel-package pinned (in a broken way) to experimental.
