yes it is. /mnt/acme is the root, hence /mnt/acme/new is in the top level. ls -l /mnt/acme does a directory read to obtain just the names of the directory entries (that's all the unix interface allows) and then stats each file in the directory, which turns into a 9p walk+stat+clunk. if you ran ls -l /mnt/acme/* in plan 9 you'd get the same behavior. the difference is that 9p has optimized the star-free case in a way that unix cannot take advantage of. russ
