archlinux /dev/disk/by-label crash

[ART]

this error happens when I try to boot with arch linux and load unetbootin grub on my netbook and also the 30 seconds error
and only look that says rootfs something like this
mounting 'dev/disk/by-label/' to `/run/archiso/bootmnt`
waiting 30 seconds for device /dev/disk/by-label/
ERROR: `/dev/disk/by-label/` device did not show up after 30 seconds...
falling back to interactive prompt
you can try to fix the problem manually, log out when you are finished
sh: can't access tty; job control turned off
rootfs#

well i had the same issue.
trying to mount 'dev/disk/by-label/' but no label is defined
after googling alot found a solution.
i solved this adding "archisolabel=LABEL_OF_YOUR_USB_DRIVE" to syslinux.cfg just after "kernel /ubnkern" in the same line from default entry. so the line becomes "kernel /ubnkern archisolabel=YOUR_LABEL"

or you can do when on interactive prompt "ls /dev/disk/by-label"
and find out the label of your usb device before editing syslinux.cfg

I come accross the same issue with newest iso.

How can i define the archisolabel in menu.lst?
