"set the resume variable"? where's that?

newbiesforever · 03-21-2021, 04:11 PM

When one upgrades certain software (as in performing an apt-get dist-upgrade after installing from a months-old snapshot, as I just did), one may see a notice identifying the resume partition, and an instruction about setting the resume variable--change in in order to make the system resume from somewhere else.

I understand changing it and why I might want to, I just never knew where the resume variable was.

I don't know that it's so much a "where" as a "what," but I'm hardly an expert.

Maybe one of these articles from kernel.org will help.

See if this file exist:
/etc/initramfs-tools/conf.d/resume

I only just got around to checking on this. The file does not exist; my /etc/initramfs-tools/conf.d/resume is empty.

It's empty because by default the initrd specifies the resume partition as the current swap partition. If you want it to be something different, you put the device there.

You can put the swap variable in, and the sky doesn't fall down. On the kernel command line:

Code:

linux  /vmlinuz-generic-5.10.15 root=/dev/sda3 ro

OR

Code:

linux  /vmlinuz-generic-5.10.15 root=/dev/sda3 resume=/dev/sda2 ro

Change of course for your root & swap partitions.
