- virtual directories, reading a directory wipes out the virtual directory. virtual property in the inode. - inode contains the qid, inuse, pointers, and virtual property. one pointer each for 3 levels. ? reserve version == -1 to mean a virtual file? makes some things easier. - first inode is always the root. - adding any virtual entry to a directory makes the whole directory virtual. ? how do we keep cfs from swapping? ? how do we resolve access to missing parts when running remotely? ? what are default properties of files (ones we haven't stat'd)?
