Package: initramfs-tools
Version: 0.130
Severity: normal
Tags: patch

Hi,

In hook-funtions, dep_add_modules_mount() wants a real mount point
while zfs only presents its mount point as a virtual one named by the
underlying dataset in /proc/mounts, this makes the function abort
claiming unable to detect the root device.

Such behavior breaks the installation of kdump-tools with zfs as
rootfs because it explictly generates a new initrd with MODULES=dep.

Attached patch makes dep_add_modules_mount() return upon detecting a
zfs rootfs. Because users who run zfs as rootfs are required to
install zfs-initramfs package, where a lot more details are handled,
there is no potential breakage for not handling zfs related kernel
modules here. If someday we have built-in support of zfs in
initramfs-tools package, this peice of code should be revisted,
though.

Regards,
Aron
