Use the archisolabel= command line option to mount the archiso device.
If the archisolabel= option is specified on the kernel commandline, a device /dev/archiso will be created and will be used to boot the live system. Patch from brain0 <thomas@archlinux.org> Signed-off-by: Gerhard Brauer <gerbra@archlinux.de> Signed-off-by: Aaron Griffin <aaronmgriffin@gmail.com>
