> midori Linux . . . includes [a good FLASH filesystem]

do LFS segments correspond well with FLASH blocks?  

If so, maybe we can just continue directing the effort toward stable LFS, 
and then make a 'lightlfscleanerd' that simply frees space, without 
trying to optimize seeking with file locality. :'

anyway, i don't really understand LFS well.

One thing that might be convenient is a way to boot with a mdroot and 
then free the memory after switching to some other root.  This would 
help with ipsec-ified nfsroot clients as well.  or, do we already have 
this capability?  I don't know how mdroot works either. :)
