Configuring the root File System and Performing the Network Boot
As well as a kernel, the Client also needs a root file system. There are several ways of serving up a root file
system to the Client, we discuss three possibilities below and show how the kernel and root file system are
put together to perform a network boot using Etherboot.
NFS Only
1. Perhaps the most flexible method for serving a root file system to a diskless client is with
NFS. To create a root file system on the Server that NFS will serve up to the Client, Cut and
Paste the script below, save it to “/usr/bin/mknfsfs”, and type,
• “dos2unix /bin/mknfsfs” #Ensure the file is in Unix format
• “chmod 755 /bin/mknfsfs” #Make the file executable
• “mknfsfs 192.67.84.171” #Creates a root file system in the /tftpboot directory
