After I had sent that, modified 40_custom, tested something with 41_custom,
I've run into a related pitfall:

  # rpmls grub2|grep ^l
  lrwxrwxrwx  /etc/grub2.cfg
  # file /etc/grub2.cfg
  /etc/grub2.cfg: symbolic link to `/boot/grub2/grub.cfg'

So, more symlink madness. /etc/grub2.cfg -> /boot/grub2/grub.cfg
and it doesn't even work flawlessly:

  # grub2-mkconfig -o /etc/grub2.cfg
  Generating grub.cfg ...
  ...
  # ls /etc/grub2.cfg 
  /etc/grub2.cfg
  #

WTF? It didn't _follow_ the symlink, it replaced it with a file.
The reboot didn't use it, of course, but used the old one in /boot/grub2.
Useless stuff.

Notice how it says "Generating grub.cfg ..." when in fact it creates a
file grub2.cfg. This is extra misleading.
