The grub2 boot loader is installed in a /boot partition in my Fedora 20
installation and works properly. But I do create 1 GB boot partitions
and maybe most people do not use as much space for their boot partition
as I do.
How hard would it really be for grub2 to check to make sure it has
enough space to install itself into a /boot partition ? I am a
programmer myself and although I do not know the code/design for the
grub2-install command I am sure such a check for /boot partition size
cannot be that hard to do.
I finally saw some posts about how to install grub2 for CentOS7 into a
/boot partition manually and I will do that. But the Anaconda installer
should never have created this headache to begin with no matter what
they say. All other Linux distros I have used, such as Suse, Mint,
Ubuntu, Mageia etc., give the ability of installing the bootloader into
a /boot partition even when defaulting to grub2. There is no excuse for
this Anaconda nonsense from Fedora other than programmer egotism.
