Public bug reported:

On a system with swap disabled (removed from /etc/fstab) and package
zram-config installed update-initramfs -u will emit something like

I: The initramfs will attempt to resume from /dev/zram1
I: (UUID=1d4b8573-7eee-43c9-a02a-10a65fc17b8a)
I: Set the RESUME variable to override this.

Obviously, resuming from zram device without actual non-volatile storage
is not going to work. update-initramfs should be fixed to ignore
/dev/zram* because otherwise the user must e.g. create file /etc
/initramfs-tools/conf.d/resume-none with case-sensitive contents


to workaround the issue, which may be a bit hard to guess from the above
notice only.
