Grub Pacnew files - questions about the new version

I was trying to work through my pacnew files to merge changes and I saw one on grub that made me pause because the pacnew version didn't make a lot of sense to me.

I am using pacdiff to see the differences and trying to determine whether to replace or merge the differences. The file on the right below is the pacnew file for /etc/default/grub, which replaces distributor of "Garuda" with "Arch" and seems to remove the garuda theme. I'm not sure how that could be the "new" file.

The files:

.rw-r--r-- 1.8k root 25 Feb 14:04 grub
.rw-r--r-- 1.8k root 21 Feb 14:55 grub.pacnew

The pacnew file is dated from Feb. 21, which the current grub file is dated from Feb. 25. Probably this is just a holdover from an earlier update that I never dealt with. I think I have an old pacnew file that I need to just delete, can someone confirm based on the contents? I am wary when it comes to messing with grub configuration.

I can't read your output :wink:

After merging it looks like this

I use this alias

alias | grep pacdif

then I use "v" and meld show me nicely both files and difference. Save your changes in meld and close, then you can skip, remove or quit. I never use overwrite

Thanks. You confirmed what version was correct, thanks.

Opps. I just found another one. /etc/mkinitcpio.conf

I have a harder time knowing what the right version is on this one.

Should the file contain MODULES="crc32c-intel"? The pacnew version has MODULES=(). Should I be looking on gitlab at the current files to see what the right version is?

I don't think this is needed any more. From https://wiki.archlinux.org/index.php/Btrfs#Checksum_hardware_acceleration:

Therefore, MODULES=() will be fine.

I just removed the new config files. It didn't seem to add anything of use. Maybe I'm wrong about this.

Yes, but this thread is solved.
