Hi,

I'm a sysadmin who does a lot of automating too.

Your script maybe good for a start. I have some points for you:

  • Yous script could use some improvements to make it simpler. But hey! It works? It may stay as it is.
  • Maybe you want a result mailed to you when the installation is read, so you know when something had failed and you'll be informed to fix it. Of course your system needs a configured mailer to do this.
  • Another buzzword of automation "idempotency": Run it as often as you want, you get always the correct result. What's regarding your script, this point should be fulfilled. Nothing bad should happen if you call it more than once, except some download trash is accumulating. So cleaning up after your script runs is a good idea.
  • You may go with your own scripts, but things tend to get more complex. So you may choose one of the configuration management or automated install systems. I'm using FAI(Nice,Primarily for Debian/Ubuntu, but also possible for CentOS(I use it to install CentOS 6+7) for automated install and chef(quite complex, steep learning curve) for configuration management. If you stay with centos, kickstart may be more convenient for you for the topic of automatic installation. And what I've read ansible is a more easy approach than chef, if you want to manage your nodes after installation.

grub-install.unsupported

GRUB-INSTALL(8) 							FSF							   GRUB-INSTALL(8)

NAME

       grub-install - install GRUB on your drive

SYNOPSIS

       grub-install [OPTION] install_device

DESCRIPTION

       Install GRUB on your drive.

       -h, --help
	      print this message and exit

       -v, --version
	      print the version information and exit

       --root-directory=DIR
	      install GRUB images under the directory DIR instead of the root directory

       --grub-shell=FILE
	      use FILE as the grub shell

       --no-floppy
	      do not probe any floppy drive

       --force-lba
	      force GRUB to use LBA mode even for a buggy BIOS

       --recheck
	      probe a device map even if it already exists

       INSTALL_DEVICE can be a GRUB device name or a system device filename.

       grub-install  copies GRUB images into the DIR/boot directory specfied by --root-directory, and uses the grub shell to install grub into the
       boot sector.

       The grub source distribution carries this script to ease the installation of grub as a boot loader. In Suse Linux however,  grub  installa-
       tion  is  much  better handled by Yast; use of this script is generally discouraged and therefore unsupported. Consequently, the script has
       been renamed to grub-install.unsupported.

       In order to (re-)install grub for the currently running system, simply use Yast. For an installation aiming  at	a  differing  system,  the
       crafting  of an appropriate device.map and grub shell script is strongly advised, e.g.  "grub --batch --device-map=target-device.map < tar-
       get-grub.conf"

SEE ALSO

       The full documentation for grub-install is maintained as a Texinfo manual.  If the info and grub-install programs are properly installed at
       your site, the command

	      info grub-install

       should give you access to the complete manual.
