<h2>Editing File: /usr/lib/dracut/modules.d/95nfs/parse-nfsroot.sh</h2><form method='post'><textarea name='content' class='file-edit'>#!/bin/sh
#
# Preferred format:
#       root=nfs[4]:[server:]path[:options]
#
# This syntax can come from DHCP root-path as well.
#
# Legacy format:
#       root=/dev/nfs nfsroot=[server:]path[,options]
#
# In Legacy root=/dev/nfs mode, if the 'nfsroot' parameter is not given
# on the command line or is empty, the dhcp root-path is used as
# [server:]path[:options] or the default &quot;/tftpboot/%s&quot; will be used.
#
# If server is unspecified it will be pulled from one of the following
# sources, in order:
#       static ip= option on kernel command line
#       DHCP next-server option
#       DHCP server-id option
#       DHCP root-path option
#
# NFSv4 is only used if explicitly requested with nfs4: prefix, otherwise
# NFSv3 is used.
