2 Problems

[IgorVian]

Using your very useful script in Manjaro, caused 2 problems: 1) grub file modified like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash $(resume_boot_option)" instead of: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=c5c38daf-e419-4f32-9b94-e1e7edb9f87d resume_offset=1677312" 2) in mkinitcpio.conf not inserted the "resume" word

I attached the original files, so you can test. Files.zip

Okay, #1 should be easy to troubleshoot, since it seems to be a case of variable not being expanded.

I'll look into these.

Well, I found a boatload of other problems as well. I think this going to be a rewrite...

[Chrysostomus]

Okay, I think I found the problem with #2...

[Chrysostomus]

Okay, found the cure and fixed a whole lot of other problems. Will be updating soon. Thanks again for this immensely useful bug report!

Okay, going to get somw sleep. Cannot upload changes yet, because I noticed that grub requires more complex logic for determining the right resume option, depending on whether device mapper names or uuid or partuuid is used.

[IgorVian]

Thanks for your quickly reply. I'm eager to see the changes!

Okay, I made some changes that should theoretically fix the issue with grub. Can you test it if it works for you?

[Chrysostomus]

Okay, I did some testing and the problem is not yet solved. The sed command that should insert kernel parameters into /etc/default/grub is somehow faulty.

[Chrysostomus]

Okay, I checked again. It works unless there is additional space at the end of kernel parameter line in /etc/default/grub.

[Chrysostomus]

Should be fixed now

I tried to run this script today but the GRUB_CMDLINE_LINUX_DEFAULT line edit does not work anymore.

Instead of the partition UUID only a whitespace is appended to that line. Could it be a variable expansion problem as already happened?

Here you can find a bash -x log of the script execution: hibernator.log

Thanks, I'll look into it.
