* Detect UEFI and Kernel Arch mismatch and add noefi to kernel
parameters in such a case, while uefi booting archboot (not in setup
script)
* Split x86_64 and i686 kernel parameter variables in uefi
grub_archboot.cfg due to above reason
* use /sys/class/dmi/id instead of dmidecode, dmidecode removed from
initramfs (bbut arch_dmidecode still exists)
* Added support for separate /usr in grub2 config, added grub2 search
hints support in config
* Re arranged bootloader menu, submenus per firmware, suffixed _bios
or _uefi_ to bootloader functions
* Minor (misc.) modifications in setup script
