Kali 2.0 Encrypted Swap issue

[aleister]

Hi everybody,

I've installed Kali 2.0 on my PC, along with another Linux distro and a Windows.
I've created for Kali a clear /boot partition and 3 other encrypted partitions: /, /home, and the [swap].
The problem is that at the first boot it all works fine, the system during the boot asked for the 3 passphrases for the encrypted partitions and it's all mounted.
But when I reboot, it only ask for the "/" and "/home" passphrases and not for the swap, and when the system boot up it doesn't mount the swap.

I figured that the problem is related to the UUID, in fact during the boot it keep saying something like:
(1 of 2) A start job is running for dev-mapper-sda8_crypt.device (1 min 3s / 1min 30 sec)
(2 of 2) A start job is running for dev-disk-by\2sa3duuid-etcetc (1 min 3s / 1min 30 sec)

I found on internet a way to fix that, basically using the commands:

blkid

to see the UUIDs of the partitions, the swap has something like PARTUUID="f3sfad3efe-08"

mkswap /dev/sda8

to generate the new UUID for the troubling swap partition
- And then I copy and paste the new UUID on the /etc/crypttab file
- I reboot the system and the swap now works, I've been asked for all the 3 passphrases and everything works fine.

But every time that I turn the computer off and on again, the problem keeps coming back. And I have to do it all again (new uuid, and restart of the computer).

Is there a way to avoid the UUID of the encrypted swap to keep changing? Or another way to permanently fix this problem of the encrypted swap?

I fixed using

 sudo mkswap /dev/mapper/swapname
