The final solution was quite simple. Attached the "init" file and the "config" 
file.

Both of these live in " /usr/src/initramfs " on my laptop.

I have 2 drives in my laptop which are both encrypted. The actual encryption 
key is in a file called 'key.iso'. You can remove those references if you want.

For completeness, the commands to create the 'key.iso' are in "create_key"
And the commands to encrypt a drive/partition/... using that key.iso are in 
"encrypt_partition"


Something neither genkernel or drucat support is to enter an encryption key 
once and use that to decrypt all the drives. This is why I looked into doing 
my own.

The part that occasionally needs to be updated is the list of dynamic 
libraries needed for the applications embedded in the initramfs.

The command I use to build that list is in the "config" file.

If you have any questions let me know.
