I am running RHEL6.4 which uses dracut-004, in that version I
commented out the checks for netroot in parse-ip-opts.sh, ifup, and
net-genrules.sh and in netroot I commented out the netroot check at
the top and delayed the netroot check at the bottom to right before
source_all netroot. I will post patch files in a second post. I
decided to look at dracut-034 to see what changes would be necessary
there, and those lines have changed to seemingly allow network in more
conidtions than 004 did, but I have not figured out if those
conditions are sufficient for me to turn on the network with a simple
command line option.
here are the patches I made to dracut-network-004-303.el6.noarch (from
the RHEL6.4 distro):
