hibernation How can I get s2disk to work, disk UUID changing after reboot.

[xspectatpr]

Hello,

I've trying to get suspend to disk to work but been unable to do so. It looks like it dumps the memory into the swap partition just fine and I'm setting the following options in the boot.cfg:

"Funtoo Linux genkernelHibernate" {
	kernel kernel[-v]
	initrd initramfs[-v]

	params += real_root=auto rootfstype=auto 
	params += real_resume=UUID=2b8cda5c-8449-4874-a3e9-583bbb0f47b3 resume=UUID=2b8cda5c-8449-4874-a3e9-583bbb0f47b3 
}

problem seems to be that the UUID for /dev/nvme0n1p2 is changing between reboots(I thought I was putting the wrong one lol) .

My guess is that, that's the reason why the kernel is not resuming. From dmesg it looks like it grub config points the UUID I configured just fine:

➜  ~ sudo dmesg |grep resu

Help very much appreciated, thanks!.

Try replacing UUID with PARTUUID=71e22c3d-02 which is not changing.

It's just in different order each time.
