Specifying the root filesystem

The logic in the initramfs allows the root filesystem to be specified a number of different ways. Two methods for setting the root filesystem are:

• Using the root= kernel command-line parameter
• Using a root-path option in DHCP
  Note: Setting the root-path option for a node in DHCP will always override any root= parameter on the kernel command line.

In either case, the actual root can be specified in three ways:

• NFS root, ie: 192.168.1.1:/var/lib/oneSIS/image,v3,tcp,rsize=8192,wsize=8192
• Local root specified by disklabel, ie: LABEL=/
• Local root specified by device, ie: /dev/hda1
