Where they always were -- it's just that you've mounted a different bit of the filesystem, so you can't see them. :) > I mean, I still see them if I do a "btrfs sub list", but how do I *get* to > them > for, say, deleting?

If you've got subvolumes outside your mounted filesystem, then you can either reach them by mounting via subvolid, or by mounting the top-level subvolume with subvolid=0 (on, say, /media/btrfs-top) and then navigating through that to the subvolume you want.
