# verification steps 1-3: installation in a chroot
I set up 2 chroots - one w/ the normal sources.list, the other w/
proposed enabled, and did a side by side install test.
$ for chroot in mantic mantic-proposed jammy jammy-proposed; do sudo chroot
$chroot apt list kdump-tools; done

Bug description:
[Impact]
When installing in a chroot environment, the kdump-tools kernel hook will
fail. This breaks certain OS image creation tools, such as BCM (which I assume
is NVIDIA Base Command Manager from context). While BCM's image generation tool
requires some additional tweaks to consume this, the proposed fix is necessary,
and should be sufficient for other tools that use chroots.
[Test Plan]
1) debootstrap a chroot environment for the target Ubuntu release
2) Install kdump-tools within that environment
3) Install a kernel package and make sure it succeeds.
4) do the same steps in a virtual machine, but with `ischroot` symlinked to
/dev/true at install time. This should simulate a system that was just
installed with an image prepared as above.
5) Then restore ischroot, and reboot.
6) Confirm the systemd service does generate an initramfs at boot, and
7) that a crash dump can be triggered afterwords.
[Where Problems Could Occur]
The solution we implemented in noble was simply to detect a chroot
environment with ischroot, and disable initramfs generation. The systemd
service will detect that an initrd is missing, and generate one on first boot.
A source of potential problems is if that does not happen for some reason,
resulting in a kdump-tools service failure on first boot.
