As far as I understood from this article, Coda uses some traditional filesystem as its lower level ? And it needs this inode access to speed up the operation ? Then why not just create a special filesystem that will not contain any data except Coda's and that will use inode numbers instead of file names ? Or, as a yet simpler approach, write a user-level library that will make its own filesystem structure in a plain file (and then it will be possible to use a disk special file as this plain file) ? -SB To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe hackers" in the body of the message
