Re: PATCH[0/5]: mkinitrd: fix network boot support

[Warren Togami <wtogami redhat com>]

Hans,

https://bugzilla.redhat.com/show_bug.cgi?id=481078
Thanks for looking at this.  I filed this bug for this issue.  I tried 
all five patches of your patches.  root=dhcp continues to fail because 
the DHCP Request lacks the root-path option.  (Confirmed by looking at 
it with tcpdump.)

I tried adding the appropriate dhclient -R option of the attached patch. 
 According to dcantrell and the dhclient man page, you have to list all 
default options before adding your custom option because using -R wipes 
out all defaults.  I might be doing something wrong though, because 
dhclient prints the syntax help at this point with this patch.
