Creating mount poinf if no exist

I use satellite receiver based on Debian. Is any possibility to create mount point (if no exist) for filesystem by appropriate entry in /etc/fstab ? I mean about situation when during update/upgrade procedure, most of system is overwrite by new version. But in this case system configuration is restored. That is most of /etc dir, including fstab too. So it would be nice to create such dir via fstab. The content of this filesystem is necessary during boot procedure so creating/mounting from script after boot is too late. Is it possible?
