CentOS 7 uses grub2, which should create /boot/grub2/grub.cfg. However,
it's missing on my VPS, even though the RPM that provides it is installed.

On my physical server at home that file exists and is maintained.
When a new kernel RPM is installed, that file should be updated, but
it's obviously not doing on the VPS - maybe it detects that it's booting
in xen and does something else.
I think I remember seeing something in the Red Hat documentation about
this. I'll see if I can dig it out...
