How do I add threadirqs to grub2?


I have two questions about grub2:

1)

I edited /etc/default/grub and added this line:

GRUB_CMDLINE_LINUX="threadirqs"

then I ran

# update-grub2

Now the /boot/grub/grub.cfg file has three instances of this line:

linux /vmlinuz-3.16.0-4-amd64 root=UUID=5ce5(elided) ro threadirqs quiet

...and no other linux /vmlinuz(whatever) line. It gets down to one of those three.

However, when I boot, the threadirqs option is never there. I can add it manually at boot time and later confirm that the kernel has indeed loaded with the option enabled, but I want to have that added correctly. How do I do that???

2)

How do I get to land a punch to the stomach of the people who turned grub into a big pile of feces? Does anyone here know where they hang out? Steve Jobs is dead, but I still have a shot with Bill Gates and the people responsible for grub2, right?

I don't do Debian, soooo ...
1) I would expect them to use update-grub (a Debian/Ubuntu-ism BTW) - you would have to scan the scripts.
2) My recollections is that the Ubuntu (nee Debian) devs drove it initially. Pretty obvious from the verbosity of the scripts.
Banging on about grub vs grub2 is a lost cause - just like systemd. We all liked the classic grub, but it was never going to measure up in the current world of UEFI, gpt ...

Run as root:

Code:
dpkg-reconfigure grub-efi
or
Code:
dpkg-reconfigure grub-pc
depending if you are running on an EFI machine or not. This will prompt you for, and add your args to the systemwide config, instead of having them wiped out.

This worked for me. Thank you!
