I was not able to complete the update to Manjaro 16.10 KDE on Dec. 11 or 12. The system was waiting for the mkinitcpio.
Now I am not able to boot at all. My system hangs. I have tried several kernels.
Generate customized manual initcpio
Users can generate an image using an alternative configuration file. For example, the following will generate an initramfs image according to the directions in /etc/mkinitcpio-custom.conf and save it at /boot/linux-custom.img.
mkinitcpio -c /etc/mkinitcpio-custom.conf -g /boot/linux-custom.img
If generating an image for a kernel other than the one currently running, add the kernel version to the command line. You can see available kernel versions in /usr/lib/modules.
mkinitcpio -g /boot/linux-custom2.img -k 3.3.0-ARCH
The primary configuration file for mkinitcpio is /etc/mkinitcpio.conf. Additionally, preset definitions are provided by kernel packages in the /etc/mkinitcpio.d directory (e.g. /etc/mkinitcpio.d/linux.preset).
Warning: lvm2, mdadm, and encrypt are NOT enabled by default. Please read this section carefully for instructions if these hooks are required.
I have no problem with Manjaro Gnome/Cinnamon/LXQt.
