Running FC17. I am attempting to track some issue with systemd, and need to change kernel options for my default grub entry to remove rhgb and quiet. I have modified the line "GRUBCMDLINELINUX_DEFAULT" in /etc/default/grub, and removed these options. I then generate the configuration with "grub2-mkconfig -o /boot/grub2/grub.cfg". The resulting configuration is unbootable, and contains neither options from "/etc/default/grub", nor from "/etc/grub.d/*".

Can anyone shed some light on my issue here?

I've done that before and it sounds like you're doing everything right. Can you post the resulting /boot/grub2/grub.cfg?

One thing to watch out for: I frequently use jed to edit /etc files, and it sometimes inserts line breaks as I type. (M-x no_mode deactivates that behavior.) I've broken grub2.cfg that way before: The text editor splits the long string of options into a new line at a space so grub2-mkconfig generates a garbled grub2.cfg.

I'd rather ask for /etc/default/grub

As i understand it, you had deleted the GRUB_COMMAND_LINUX. IF that line is missing or incorrect, you wont be able to boot.

Hi: For me have always worked this

sudo su -
grub2-mkconfig > /boot/grub2/grub.cfg

Hope it works.

Kind regards
