I do like the setup where the extended features are done as a "view" on top of some other filesystem, so that you can choose to _either_ access the raw (and supposedly stable, simply by virtue of simplicity) or the "fancy" interface. Without having to reformat the disk to a filesystem you don't trust, or you have other reasons you can't use (disk sharing with other systems, whatever). It doesn't have to be "user", btw, in the sense that a lot of the normal code could be in kernel mode. Same way as Tux handling all the regular static requests entirely in kernel mode, but having the ability for calling down to apache.. Linus
