Under the DEC !UNIX OSes, file versioning was just a way of life since it was on all the time for everyone, period. Trying to apply that to UNIX, where file versionioning previously didn't exist?

The way digital did it is spot on, however, the use of ; is a problem once you apply UNIX/POSIX filesystem requirements to it. It may not work. On the other hand ODS *is* an RDBMS really, so................. ;) -brian _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
