CFS and CGD have a different model. I only use my Laptop to work at
and store all my data on /home. If I need to access that data, eg. a
CVS directory for a customer or slides for a presentation at a
Conference, I have to mount /home. Therefor, I have to config the CGD
device. At that moment, all files on /home are unprotected.=20

CFS works on the normal file system layer, so I use it to protect
sensitive data, like my mailbox or PGP-Keys. I can cgdconfig and mount
my home to access my not-that-sensitive data, but still keep my very
sensitive data protected by CFS.=20

Even if someone hacks into my laptop while being at a conference,
sensitive data is still encrypted with cfs.=20
That's why I combine both models.=20

Hope that helps,
