I'm looking for a tutorial (with clear steps) similar to the following article, but using ext4 and GPT partition tables.
I will be doing a new installation of 14.04 LTS on brand new disks. I will be upgrading to 16.04 very soon.
I have an SSD and HDD. Both should be fully encrypted. Both should be accessible after entering a single passphrase on bootup. (A key on a USB stick would be acceptable too.)
The SSD will hold these partitions:
/boot (I assume unencrypted)
and all the usual directories in the Linux file system
The HDD will be mainly for pictures, audio, video, .deb files, zipped files, backups, etc.
