Package: kernel-package
Version: 12.033
severity: medium
Hello Manoj,
from time to time I build kernels with kernel-package. Since the new
kernel-package version (I installed squeeze's version to my lenny
machine) I cannot build packages anymore that automatically create an
initrd. I already read the docs and the man package I did what is
recommended to do, but I still don't get hook scripts
in /etc/kernel/foobar....
My questions:
* Does the --initrd option of make-kpkg _only_ enable the scan and
execution of the the hooks in /etc/kernel?
* Is there any mode in that creates a kernel package which _installs_
hook scripts on the _target_ system? I want the hooks script itself
being included in the kernel package I create. I see make-kpkg creates
debian/linux-image-foobar/etc/kernel/postinst.d/, but this dir is
always empty.
* Are you aware that the initramfs-tools ship a hook that contains:
---8<---
# kernel-package passes an extra arg; hack to not run under
kernel-package
[ -z "$2" ] || exit 0
---8<---
So that hook script exit 0 when called by a kernel package made by
make-kpkg - why would it be wrong to run that hook when installing a
kernel made by kernel-package?
My goal is to create distro-like kernel packages, i.e. I want the
packages to be transferable to other machines as a drop-in replacement
for the packages that Debian ships. But as long as the
users habe to call the mkinitramfs manually, it's a real pitfall for
them ...
Best Regards,
Andreas

| --initrd
| If make-kpkg is generating a kernel-image package, arrange to
| convey to the hook scripts run from the post installation
| maintainer scripts that this image requires an initrd, and that
| the initrd generation hook scripts should not short circuit
| early. Without this option, the example initramfs hook scripts
| bundled in with kernel-package will take no action on
| installation. The same effect can be achieved by setting the
| environment variable INITRD to any non empty value. Please note
| that unless there are hook scripts in /etc/kernel or added into
| the hook script parameter of /etc/kernel-img.conf. no initrd
| will be created (the bundled in example scripts are just
| examples -- user action is required before anything happens).
`----
,----[ /usr/share/doc/kernel-package/README.gz ]
| gotchas. Note that you will have to arrange for the actual
| initrd creation to take place by installing a script like
| /usr/share/kernel-package/examples/etc/kernel/post{inst,rm}.d/yaird
| or, alternately,
| /usr/share/kernel-package/examples/etc/kernel/post{inst,rm}.d/initramfs
| into the corresponding directories /etc/kernel/post{inst,rm}.d,
| since the kernel-postinst does not arrange for the initramfs
| creator to be called. You can thus select your own;
| initramfs-tools or yaird.
|
| Let me repeat:
| Since nothing is created automatically. you need to provide a hook
| script for things to happen when you install the kernel image
| package. The user provides such scripts. For example, to invoke
| mkinitramfs, I did:
| --8<---------------cut here---------------start------------->8---
| cp /usr/share/kernel-package/examples/etc/kernel/postinst.d/yaird \
| /etc/kernel/postinst.d/
| cp /usr/share/kernel-package/examples/etc/kernel/postrm.d/yaird \
| /etc/kernel/postrm.d/
| --8<---------------cut here---------------end--------------->8---
|
| Or, alternately, you could do:
| --8<---------------cut here---------------start------------->8---
| cp /usr/share/kernel-package/examples/etc/kernel/postinst.d/initramfs \
| /etc/kernel/postinst.d/
| cp /usr/share/kernel-package/examples/etc/kernel/postrm.d/initramfs \
| /etc/kernel/postrm.d/
| --8<---------------cut here---------------end--------------->8---
|
| These scripts above to nothing unless the corresponding
| packages are installed (initramfs-tools or yaird), so you could
| potentially cp both over -- as long as you never install both yaird
| and initramfs-tools at the same time.
|
| To run grub, I have in /etc/kernel-img.conf:
| --8<---------------cut here---------------start------------->8---
| postinst_hook = update-grub
| postrm_hook = update-grub
| --8<---------------cut here---------------end--------------->8---
|
| You can look at other example in the examples directory:
| /usr/share/kernel-package/examples/ to see if there are other example
| script you want to cp into /etc/kernel -- and you can create your own
| scripts.
|
| For example, if you use linux-headers-* packages to compile third
| party modules so that you do not have to keep the sources directory
| around, you might be interested in:
| --8<---------------cut here---------------start------------->8---
| /etc/kernel/header_postinst.d/link
| /etc/kernel/header_postrm.d/link
| /etc/kernel/header_prerm.d/link
| /etc/kernel/postinst.d/force-build-link
| /etc/kernel/postrm.d/force-build-link
| --8<---------------cut here---------------end--------------->8---
|
| These scripts will try to make sure that the symlink
| /lib/modules/$VERSION/build
| is sane -- that is points to the header packages whether you install
| the image packages first, or the header packages first -- and takes
| care of cleanup when either of the packages are installed.
