Package: kdump-tools
Version: 1:1.6.1-1
Followup-For: Bug #856594
Dear Maintainer,
Our use-case is exactly as the original report:
* We debootstrap into temporary folder
* Than we configure apt inside this folder and use "apt-get install....."
* The post-install of "kdump-tools" fails
The fix that was pointed by comment#15 only solve part of the issue:
* It uses the "linux-version list" command to see if a specific kernel
version is installed.
* But the issue only happen when we install both kernel and kdump-tools
As a test, I removed the kernel from the chroot and was able to
install kdump-tools without issues (even with kdump-tools 1:1.6.1-1)
Moreover, in my variant of the issue:
* Trying to run /etc/kernel/postinst.d/kdump-tools <version>
fails with the following error:
# /etc/kernel/postinst.d/kdump-tools 4.9.0-8-amd64
kdump-tools: Generating /var/lib/kdump/initrd.img-4.9.0-8-amd64
mkinitramfs: MODULES dep requires mounted sysfs on /sys
update-initramfs: failed for with 1.
* I.e:
- /sys is not mounted inside the chroot
- This is correct, as I do not want package installation inside
the chroot to touch my host /sys
IMO,
* The post-install script should skip initramfs generation if inside a chroot
* The "udevd" package has a nice "chrooted()" shell test inside their postinst
(based on comparing inode numbers of our "/" with pid-1 "/")
* Alternatively, it should check if /sys is mounted
