I don’t think this will work…
cp -a /home /dev/mapper/home

You have to mount it first.

An alternative way of setting up encrypted filesystems is to use ‘cryptmount’, which provides a friendlier front-end to the dm-crypt facilities within the Linux kernel.
This avoids having to separately execute ‘cryptsetup luksOpen /dev/sd???’ then ‘mount /dev/mapper/???’, after becoming root. Instead, cryptmount allows an ordinary user have these actions performed easily and securely simply by executing somthing like ‘cryptmount MyFileSystem’ whenever they want to mount the filesystem. This also means that the filesystem does not need to be opened every time the user boots-up or logs-in, as would be the case with pam_mount.

How about ZFS and its ZFS on disk encryption support
http://opensolaris.org/os/project/zfs-crypto/
Maybe I should do a howto on it ?

A somehow more straight forward solution for Gentoo linux can be found on http://thewinningmove.blogspot.com/2008/04/encrypting-root-swap-partitions-on.html
It works for my IBM T43, but not for T60. Anyway.

Under the section:
Mapping the drive and creating a filesystem.

The command:
root@host:~# cryptsetup luksOpen /dev/hdc6
resulted in the usage notes and the error:
cryptsetup: luksOpen: requires as arguments

The solution was the command:
root@host:~# cryptsetup luksOpen /dev/hdc6 home

I am using openSUSE 10.3 on an IBM ThinkPad A22m

I had to add the @include common-pammount to /etc/pam.d/kdm so that it worked with kde otherwise it only worked when i did console logins

i also used the /dev/disk/by-id device as i’m using this on an sd card on an eee

Here is another couple of good tutorials about encrypting filesystems over partitions and files:
