Bug Description

I tried to switch from a normal swap to an encrypted one but the command freezes after the message "cryptdisks stop/waiting":
----
$ sudo ecryptfs-setup-swap
[sudo] password for <user>:

WARNING:
An encrypted swap is required to help ensure that encrypted files are not leaked to disk in an unencrypted format.

HOWEVER, THE SWAP ENCRYPTION CONFIGURATION PRODUCED BY THIS PROGRAM WILL BREAK HIBERNATE/RESUME ON THIS SYSTEM!

NOTE: Your suspend/resume capabilities will not be affected.

Do you want to proceed with encrypting your swap? [y/N]: y

INFO: Setting up swap: [/dev/sda2]
WARNING: Commented out your unencrypted swap from /etc/fstab
cryptdisks stop/waiting

So, I tried to execute
$ sudo /etc/init.d/cryptdisks stop
and got
cryptdisks stop/waiting
instantaneously. So stopping works fine. In fact, when I tried it for a second time, I got
$ sudo /etc/init.d/cryptdisks stop
stop: Unknown instance:

On the other hand, starting freezes:
$ sudo /etc/init.d/cryptdisks start
(nothing is shown after that is executed)

FYI: this is on Ubuntu Studio 14.10.

Got the same as #1 on fresh Ubuntu 14.10 install after creating a encrypted home.

I enabled swap successfully running:

$/etc/init.d/cryptdisks force-start

and
$ free -m
returned:

I get the same issue as #1, however +Maciek's solution to force-start cryptdisks doesn't quite work.

It starts the service however when I run 'free -m' it shows my swap file size as 0, despite it being 1gb in size.
