Potential for loss of access to dual boot OSs

[WhichWitch62]

Hello,

I have dual boot configuration with access via grub for windows 7 and kali 2.0 LUKS - I have a disconcerting warning after i run sudo apt-get upgrade that can be seen below (last line):
info: 4.8.0-kali2-amd64 #1 SMP Debian 4.8.11-1kali1 (2016-12-08) x86_64 GNU/Linux
fully up to date on apt-get update, apt-get upgrade, and apt-get dist-upgrade, also apt-get autoclean, and apt-get auto-remove


Setting up lvm2 (2.02.168-1) ...
update-initramfs: deferring update (trigger activated)
Processing triggers for libc-bin (2.24-8) ...
Processing triggers for initramfs-tools (0.126) ...
update-initramfs: Generating /boot/initrd.img-4.8.0-kali2-amd64
WARNING: Setting CRYPTSETUP in /etc/initramfs-tools/initramfs.conf is deprecated and will be removed in a future release! Use /etc/cryptsetup-initramfs/conf-hook instead.

Is there any other information that would be helpful?

Any help would be greatly appreciated

I have seen that warning aswell and I am also using 2 os's (kali and Windows 7) and they still work, so I don't think that it is something to worry about.
