- Separated x86_64 and i686 specific code in all-in-one script so that a x86_64 only iso can be created if needed. - revamp grub2 uefi config used in all-in-one and update-iso scripts - added "gpt loglevel=7" to kernel parameters - Enabled xz compression for packages squashfs files - xz initramfs (in archboot-update-iso.sh) - used INITRD option in syslinux config files - change PREFIX for GRUB2_UEFI in setup script to /boot/grub as per changes in grub2 bzr r3856 (upstream), package will be in the repos shortly - disable get_grub2_map() , grub-mkdevicemap removed by upstream in r3856 - revamp dogrub2_config function - common config for both grub2-bios and grub2 uefi in setup script (required r3856 pkg) - use sgdisk alone for auto_prepare gpt in setup script - increase UEFISYS part size to 512 MiB in auto_prepare in setup script (required for alternate UEFI bootloaders) - fix repeating .efi in efibootmgr command in setup script - other minor fixes, added quotes whereever required - [TRIED TO] fix quickinst script
