[X2Go-User] Centos 7

[Robert Dinse]

      Something still isn't right, missing the step to create initramfs,
so I added:

 	mkinitrd initramfs-3.19.3-kg-1 3.19.3-kg-1

      It creates it but when I run:

 	grub2-mkconfig -o /boot/grub2/grub.cfg

      It doesn't see it:

Generating grub configuration file ...
Found linux image: /boot/vmlinuz-3.19.3-kg-1
Found linux image: /boot/vmlinuz-3.19.3-1.el7.elrepo.x86_64
Found initrd image: /boot/initramfs-3.19.3-1.el7.elrepo.x86_64.img
Found linux image: /boot/vmlinuz-0-rescue-10a4840ccefb6d2f7accde9f4562308f
Found initrd image: /boot/initramfs-0-rescue-10a4840ccefb6d2f7accde9f4562308f.im

      It finds the vmlinuz but not the initramfs.  Is there some conf file I
have to add that to?  Sorry not much experience with grub2 by hand, just the
old grub, and the make file does the right thing on the Debian based machines.

      The kernel I'm trying to add is vmlinuz-3.19.3-kg-1
