Is this referring to the ecryptfs-utils package, or the kernel module, or both? Can  eCryptfs be used on an Amazon EC2 instance, and if so, how do I get the kernel module installed?


I don't have F21 up right now but I do have an F22 image running. For
F22 ecryptfs kernel module is in the kernel-modules package. You need
to install the kernel-modules packages for the kernel that is running
and then you can insert the module. I don't know if this is the same
case for F21 or not but check and see if that works for you.

Hope this helps,
