man 8 cryptsetup...
The only customization you will need is to remove the link to
/etc/init.d/cryptdisks from your start runlevel so that the system
doesn't stop and request a password during the boot process...
When your system has finished booting, log in and run
/etc/init.d/cryptdisks
enter the password, and finally mount the encrypted filesystem.
In my opinion it would be better if cryptdisks actually did the
mounting (as I believe /etc/init.d/boot.crypto does on SuSE).
It seems in Debian there is an assumption that someone will be
on hand to enter a password at boot time, so that the normal
fstab 'mount -a' can be used to mount it.
For me it makes sense to delay the mount, not just to avoid preventing
a successful unatended reboot, but because if data is sensitive enough
to store on an encrypted filesystem, it should only be mounted when
needed...
