Arch Linux

Description:
The following line currently exists in /usr/lib/initcpio/install/lvm2
sed -i '/^\smonitoring =/s/1/0/' "${BUILDROOT}/etc/lvm/lvm.conf"

This line doesn't do anything because the sed pattern doesn't match.
The line it's trying to modify in /etc/lvm/lvm.conf is # monitoring = 1
and the leading # causes the pattern to not match.

This means that any lvm operation in early boot will try to talk to dmeventd and fail to do so.

I propose changing the line to be the following sed command:
sed -i 's/^\(\s\+\)#\? monitoring = [[:digit:]]\+\s*$/\1monitoring = 0/' "${BUILDROOT}/etc/lvm/lvm.conf"


Additional info:
* package version(s) 2.03.16-1

Steps to reproduce:
pacman -S lvm2
add lvm2 to the HOOKS section in /etc/mkinitcpio.conf
Build the initramfs mkinitcpio -P
Unpack the initramfs with cpio -id < your_initramfs
Navigate to etc/lvm/lvm.conf and note that the conf has not been changed - it is still a commented out # monitoring = 1
