Whenever initramfs is updated I get a message similar to this:

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.

However, because all my swap partitions are zram devices, I would like to disable resume. How can I do that?

You can disable resuming from swap devices by adding RESUME=none to the initramfs configuration.

Put this into a file named /etc/initramfs-tools/conf.d/noresume.conf:

# Disable resume (this system has no swap)
RESUME=none

    Note that the value none is case-sensitive. Some other pages contain messages telling to use RESUME=NONE, which is incorrect. – Mikko Rantalainen Jan 11 '19 at 17:09

    @MikkoRantalainen, you can check if you used the correct casing by running sudo update-initramfs -u – smac89 Mar 3 '19 at 22:14
  • this is not working for me in 18.04. I get the same delay, with error message that it gave up waiting for suspend/resume device. – Tim Richardson Oct 18 '19 at 1:08
  • @TimRichardson what does update-initramfs -u say? – Andrea Corbellini Oct 20 '19 at 16:25
