>Description:
        boot loader is unforgiving to extra spaces in boot.cfg
        Randolf Richardson found it and wrote these instructions:

        "Modify your /boot.cfg file so that it looks like this one here
        (in particular, DO NOT insert a space before the word "load"
        or else the boot process will fail)..."

        menu=Boot Xen 3.3:load /netbsd-XEN3_DOM0 console=pc;multiboot /xen.gz 
dom0_mem=2048M

        Indeed if you insert space before "load," boot fails.
        This may trap unsuspecting user (even experienced one)
        and make him to waste time on solving non-existent problems.
>How-To-Repeat:
        Put the following line into /boot.cfg and try to boot:

        menu=Boot Xen 3.3: load /netbsd-XEN3_DOM0 console=pc; multiboot /xen.gz 
dom0_mem=2048M
>Fix:
        Remove leading and trailing blank space from fields?
