Hi,
I made two scripts to customize a master and enabled a “Fog Service” in ubuntu.
I used it in dual boot configuration (Win7/Ubuntu 14.04)
The first script - Cutom_My_Master (only launch on the master to prepare image) :
- Update host (apt-get update / upgrade)
- Modify Grub : Set timeout to 30s and default boot
- Modify Gnome authentication : Disable login history
- Enable Fog Service : add a service that allow to modify hostname, domain at startup/shutdown
- Display a cool Hello Kitty at end (It was to justify my daughter why I was working at home)
The second script - host_rename_fog (it’s the “FOG client”) :
- It’s installed as a service
- Update hostname and domain by contacting Fog Mysql Server (at startup/shutdown)
-> Detect all networks cards and check if a mac address is present in Fog. If the hostname or domain is different it apply the update
->Turn all interfaces in DHCP in /etc/network/interface
-> Updating /etc/hosts and /etc/hostname
-> Remove persistent cards, very usefull in deployment
-> Automatically restart machine to apply modification, and modify default boot to ubuntu once time.
Howto :
1/ Copy paste the code below in two files (saved in the same folder) : Custom_My_Master (in my case) and rename_host_fog (the name is important for this file, it’s used to declare the script in the init process).
2/ Change right of Custom_My_Master : chmod 755 Custom_My_Master
3/ Modify the rename_host_fog to match with your fog installation
4/ Run Custom_My_Master : ./Custom_My_Master
Scripts :
Custom_My_Master
