nfs root file system

• NFS-Root mini-HOWTO
• Mounting the root filesystem via NFS (nfsroot)
• Documentation / filesystems / nfsroot.txt

root=/dev/nfs rootfstype=nfs rw nfsroot=[<server-ip>:]<root-dir>[,<nfs-options>] ip=<client-ip>:<server-ip>:<gw-ip>:<netmask>:<hostname>:<device>:<autoconf>

• The <autoconf> parameter can appear alone as the value to the ‘ip’ parameter (without all the ':' characters before). If the value is "ip=off" or "ip=none", no autoconfiguration will take place, otherwise autoconfiguration will take place. The most common way to use this is "ip=dhcp".
