I have just downloaded and installed a fresh Ubuntu 17.10 server system.
sudo apt update and
sudo apt upgrade I happened to notice these two warnings:
WARNING: Setting CRYPTSETUP in /etc/initramfs-tools/initramfs.conf is deprecated and will stop working in the future. Use /etc/cryptsetup-initramfs/conf-hook instead.
cryptsetup: WARNING: target cryptswap1 has a random key, skipped
I have no idea what this is, but I would like to prevent any trouble in the future. Note that I'm using full disk encryption, I assume this has to do with that. If I check the
/etc/initramfs-tools/initramfs.conf file, the string
crypt does not occur at all.
What am I supposed to do? And the fact that my swap partition is using a random key (at least that's how I interpret that warning), it that supposed to be the case? If not, how do I fix that?
