Great work guys, I've been lurking till it was at a more friendly level to install, looks like its there so I'm having a go.

just in case any one else had problems, when partitioning, the <fat32> number is "blocks of 1024 bytes" , so for mine I wanted 2.1gb so i put ",2100,C"

Also I needed to reboot after running the sfdisk command before I could run the mkdosfs or mke2fs command. (the umount command failed too)

Hope it helps some one else.
