Just had a friend of mine who was having issues with loop mounting. We ship with archiso_loop_mnt but being an vaft formatted device he needed to add MODULES="nls_iso8859-1" to mkinitcpio.conf. Thought I would try for myself and once I had got LABEL set on device, booted via grub. Only to be dropped to reduced shell as it could not find aitab? grub.cfg set timeout=10 set default=0 menuentry "Archbang 2014.05.01 (x86_64)" { set FILE=/boot/isos/archbang-rc-2014.05.01-x86_64.iso loopback loop $FILE linux (loop)/arch/boot/x86_64/vmlinuz img_loop=$FILE img_dev=/dev/disk/by-label/ARCHBANG archisolabel=ARCHBANG archisobasedir=arch # for Vesa mode... add: xorg=visa nomodeset initrd (loop)/arch/boot/x86_64/archiso.img } This is config I found on Archlinux forums, not that much information in wiki (that I could find) Is the config incorrect? Are there are problems related to loop? MrG
