A hacker who has root can forcibly unmount the cdrom and mount another directory on that node. Not a good solution.
As soon as the sysadmin finds out, said directory can be unmounted and CD-ROM device can be remounted. Besides, if someone manages to get root access on any machine, the sysadmin of that machine is basically screwed anyway. It's much better than having to back up the web page on a tape and having to restore the data when it is altered.
It depends on the ratio R = (frequency of legit Web page changes) / (frequency of breakins * cost of a breakin). The lower is R, the more what you say makes sense. I suspect that in the real world R is rather high. - Igor.
