Unfortunately, just like other RW media DVD-RAM won't work for this purpose - they all allow complete deletion/overwrite of files & inodes, which is unacceptable for WORM (write-once, read-many). The drawback of the media "getting smaller and smaller as files are deleted" would be considered a feature, especially considering many people *never* want certain files (esp. logs) deleted, regardless of who attempts to do so. Imagine, if you will, the following scenario: 1. Mount DVD-R via pktcdvd under /var/log/WORM 2. Direct syslog daemon to write a copy of all log files to /var/log/WORM/somefilename 3. System is compromised, attacker attempts to [clumsily] erase their tracks by removing log files 4. Logs are recoverable by adding '-o unhide,undelete' when mounting the DVD from another system during post-mortem. Of course, a simple cron job similar to tape-change reminders would have to be set up to aid in managing the space available, but that would be the easiest part. If someone tried to be more subtle and just modify part of a file, it would be terribly obvious as well, since an inode out of the middle of a previously linear file would suddenly leapfrog forward. I'm sure there are additional use scenarios, but this is the specific one I'm trying to address and am bit surprised that no one seems to have brought it up before. I can see & understand everyone's fascination with rewritable media as cheap temporary storage, but a readily available, cheap storage medium that is _physically_ immutable short of destruction has equally fascinating applications, especially if we were able to write to it incrementally.
