[SOLVED] Boot problem after updating the system (lvm2 and readline)

Hello folks!

After updating Archlinux a few minutes ago (in which the kernel has been updated from the version 4.8.7 to 4.8.8)
the system can't boot anymore because it doesn't find the root device.
Here are the console messages:

:: running early hook [udev]
starting version 231
:: running early hook [lvm2]
:: running hook [udev]
:: Triggering uevents...
Waiting 10 seconds for device /dev/diskby-uuid/b407a96c-8393-4559-9876-d72e5d0f532f ...
ERROR: device 'UUID=b407a96c-8393-4559-9876-d72e5d0f532f' not found. Skipping fsck.
ERROR: Unable to find root device 'UUID=b407a96c-8393-4559-9876-d72e5d0f532f' .
You are being dropped to a secondary shell
    Type 'exit' to try and continue booting
sh: cant't access tty; job control turned off
[rootfs ]#

Any idea how the problem can be solved efficiently.

Regards
Nik

Re: [SOLVED] Boot problem after updating the system (lvm2 and readline)

After reading similar threads which are pointing to a dependency error reported here (FS#51818 - [lvm2] readline 7 breaks lvm2)
I checked it on my system and found exactly the same problem:

 ==> ERROR: binary dependency `libreadline.so.6' not found for `/usr/bin/lvm'

Here is my dirty workaround for that problem: After booting the system using Arch CD and mounting
the filesystems and doing a arch-chroot I've created a link libreadline.so.6 --> libreadline.so.7
and generated a new initramfs (mkinitcpio -p linux).

Afterwards I could boot the system!

There is other threads with the real answer to this problem, which just involves running mkinitcpio. I would undo this change and fix the issue that way to avoid trouble down the road.

Re: [SOLVED] Boot problem after updating the system (lvm2 and readline)

which thread do you mean concretely?

I have removed the link and generated the initramfs again and rebooted the system.
It worked!
