CentOS 7 Failed saving grub configuration!

[Robert Moggach]

I have a fresh yum install of grub-customizer and making adjustments to a vanilla grub2 config.

Looks like whomever is the maintainer for the fedora rpm needs to customize for rhel/centos.

The following dialog pops up on save:

Failed saving grub configuration!

Please take a look at the command line output below. If you think this is a bug of Grub Customizer, please create one at https://launchpad.net/grub-customizer! Generally Grub Customizer should prevent errors like this.

failed running 'grub2-mkconfig -o "/boot/efi/EFI/fedora/grub.cfg"' output:

What we need for this is sane defaults for each OS in the environment setup

OR

Error Reporting that better describes the steps that can be taken... ie. customize your environment with some documentation for common configurations eg. CentOS vs. Fedora vs. Ubuntu vs. Mint etc. etc

Changing the environment by swapping fedora for centos in the paths has no effect:

OK... so changing the environment paths in the GUI... remembering to check save this environmment which is off by default... then quitting and relaunching... seems to work. Still I think there's a bug in the workflow here that should be adjusted so paths on centos are correct out of the box.
