Please install a \e[1mbootloader\e[m. Edit the appropriate config file for
your loader. Please use \e[1m${_VMLINUZ}\e[m as kernel image.
Chroot into your system to install it:
  \e[1m# mount -o bind /dev ${_DESTDIR}/dev\e[m
  \e[1m# mount -t proc none ${_DESTDIR}/proc\e[m
  \e[1m# mount -t sysfs none ${_DESTDIR}/sys\e[m
  \e[1m# chroot ${_DESTDIR} /bin/bash\e[m

Next step, initramfs setup:
Edit your \e[1m/etc/mkinitcpio.conf\e[m to fit your needs. After that run:
  \e[1m# mkinitcpio -p ${_KERNELPKG}\e[m

Then \e[1mexit\e[m your chroot shell, edit \e[1m${_DESTDIR}/etc/fstab\e[m and \e[1mreboot\e[m!"
