I do a make release then run this script on the resulting DVD 
directory..
http://www.gsoft.com.au/~doconnor/makeusb.sh

ie..
/tmp/makeusb.sh /tmp/${RELNAME}-release/R/cdrom/dvd1 /dev/da1

Then mount it onto /mnt and do
cp -r /tmp/${RELNAME}-release/R/cdrom/dvd1/${BUILDNAME} /mnt

It creates an MFS using makefs which syslinux can load and then the 
loader runs, loads the kernel and the MFS (nested MFS - bleh) and then 
boots as usual for an install.

Once the kernel starts the USB stick is accessable as daX as a FAT 
partition.

I have tried getting syslinux to just run the loader from an MFS (which 
works) but I can't get the loader to read the USB stick for some reason 
even though AFAICS it should grok FAT32 disks. I didn't really know how 
to debug it any further though so I went with the less elegant MFS in 
MFS route.

Also I imagine gpart could be used (in HEAD anyway) instead of the fdisk 
voodoo I have.

Note that while it references logo.lss it doesn't actually copy it over 
(it's my company's logo, but anything would suffice and it's optional - 
syslinux ignores the directive if the file doesn't exist)

I hope you find it useful and it gets in the tree :)

Thanks.
