Maybe some are even useful. What "we" really want is a good implementation (or maybe even documentation :-) ) of the stackable filesystem layers as described in: Stackable Layers: An Architecture for File System Development, John Shelby Heidemann, UCLA, 1991. Apparently it is available on-line as ftp.cs.ucla.edu:pub/ficus/ucla_csd_910056.ps Hans -- H. Zuidam E-Mail: hans@brandinnovators.com Brand Innovators B.V. P-Mail: P.O.
