Hmm... [my Flash doesn't have space for jffs2 :-( ]
I wonder why they think it's required.

Still: if you do use the jffs2, then having the jffs2 in there is quite
compatible with "little point in including lots of stuff in your
squashfs": are there going to be modules in your squashfs that are not
used before mounting the external rootfs, and if so what good are they?

In which sense is it less safe than your flash firmware after you've
set the config file to mount the external rootfs?
Also, you can easily make it fallback on squashfs+tmpfs if the
partition is not found (after some timeout, let's say) or if the
partition is found but without /sbin/init. So at least for USB drives,
you can just disconnect the drive while booting to fallback to
a safe state.
And there's always the failsafe mode as well.
[ Still talking from my experience with a WL-700gE where a jffs2 was
not an option. And in my case, disconnecting the drive was not really
an option since it's IDE. ]

Wonderful, tho I missed that email.
