Public bug reported:
Package lvm2 contains a init-premount script named /usr/share/initramfs-
tools/scripts/init-premount/lvm2
In this script there is the function call:
add_mountroot_fail_hook "20-lvm2"
Which is defined in /usr/share/initramfs-tools/scripts/functions
In focal's 0.136ubuntu6 , this is defined as:
add_mountroot_fail_hook()
{
mkdir -p /tmp/mountroot-fail-hooks.d
ln -s "$0" /tmp/mountroot-fail-hooks.d/"$0"
}
The final line of the function will execute as
ln -s "/scripts/lvm2" /tmp/mountroot-fail-hooks.d/"/scripts/lvm2"
And fail, because directory /tmp/mountroot-fail-hooks.d/scripts does not
exist.
It is clear from lvm2's invocation that it expects the symlink to be
named "20-lvm2" , and if we look at bionic's 0.130ubuntu3.6 that is the
case:
add_mountroot_fail_hook()
{
mkdir -p /tmp/mountroot-fail-hooks.d
ln -s "$0" /tmp/mountroot-fail-hooks.d/"$1"
}
focal's version needs to be updated to either support the "$1" argument
or strip the directory from "$0".
