[dm-crypt] Auto Mounting when file accessed?

Is there a known method, when a user accesses a file/folder of an
unmounted dm-crypt partition, the action can spawn an attempt to automatically
mount this partition.

For the password prompt, as I constantly am working within a terminal and not
GUI desktop for obvious reasons, pinentry is commonly used for prompting in a
terminal or by GUI for a password when using GNUPG.

Any thoughts on this?  (Kernel DBUS/UDEV script or something?)


The type of current setup targeted is a file containing an encrypted EXT3
filesystem using dm-crypt, for which is mounted to /mnt/crypt.

This is usually left in an unmounted state until wanting access to something
within /mnt/crypt/somefile/orfolder.

ie. "vi /mnt/crypt/myfile or abook /mnt/crypt/addressbook --datafile
/home/roger/.abook/addressbook"


I'm thinking, something within the dbus/udev (kernel script) is needed.
Another thought, what if TAB Bash Completion is used?
