Step 4 – Setup Completion To complete the setup, create the nrcswg userid and then reboot the PC. 2.4.1. The nrcswg user A nrcswg user account is created to minimize the customization of paths used in various configuration files. All common files will be located under the nrcswg directory created for this account. The directory structure to be created under /home/nrcswg is shown below: NRC_Dev_Env_Setup_Guide_v1.0 Status: Released 13 Figure 1-4. Install /home/nrcswg |--target |-- baselinefs |-- workingfs |-- kernel |-- tftpboot |-- nfs To create the nrcswg user, go to System Settings -> Users and Groups. Click on the Add User button, and enter following: 1. User Name: nrcswg 2. Password: type_password_here 3. Confirm Password: type_password_here 4. Uncheck the Create a private group for the user option 5. Click OK to continue The next step is to add your the development account (not the nrcswg account) to the users group. Highlight your user account, and than click the Properties button. Choose the Groups tab and check the users group. Click OK to continue. The nrcswg account should be modified in order for you to have write access from your user account. Open a terminal window, login as root, and type: 1. cd .. 2. chmod 770 nrcswg You should now reboot your PC before continuing. After the PC reboots, login as the development user, open a terminal, change to the nrcswg directory (cd /home/nrcswg) and enter the following commands: 1. mkdir target 2. cd target 3. mkdir baselinefs workingfs kernel tftpboot tools tmp 2.4.2. PXELINUX Boot Loader Set-up PXE (Preboot eXecution Environment) allows the target to boot a Linux image retrieved over a network using information supplied by a DHCP server and then using tftp to retrieve the image. PXE is part of an Intel initiative called Wired for Management. The Wired for Management (WfM) initiative enables such features as instrumentation, use of the network as a boot device, remote wake-up, and power management.
