What image is on the Yun as shipped?

Actually, which of the images you get when building Linino is the closest to the one on the Yun when shipped? I think the openwrt-ar71xx-generic-linino-16M-squashfs-sysupgrade.bin is the best to flash, can someone confirm?

Is there a summary of the different functionality of the images somewhere on the 'net?

Here is what I find in my trunk/bin/ar71xx after I build:
openwrt-ar71xx-generic-linino-16M-jffs2-sysupgrade.bin
openwrt-ar71xx-generic-linino-16M-kernel.bin
openwrt-ar71xx-generic-linino-16M-rootfs-jffs2.bin

openwrt-ar71xx-generic-linino-16M-squashfs-sysupgrade.bin
openwrt-ar71xx-generic-linino-caldata.bin

openwrt-ar71xx-generic-rootfs.tar.gz
openwrt-ar71xx-generic-root.jffs2-128k

openwrt-ar71xx-generic-root.jffs2-64k
openwrt-ar71xx-generic-root.squashfs
openwrt-ar71xx-generic-root.squashfs-64k
openwrt-ar71xx-generic-uImage-gzip.bin
openwrt-ar71xx-generic-uImage-lzma.bin
openwrt-ar71xx-generic-vmlinux.bin

openwrt-ar71xx-generic-vmlinux.gz
openwrt-ar71xx-generic-vmlinux.lzma

It could be great to have this information... may be linino web will give us this info when it launch... is there anyone who knows when the linino web will be up???
