[gPXE-devel] [PATCH] hierarchal friendly settings_ui

[Glenn Brown]

[This is a resend, since my previous send never reached the list...]

Here are screen shots showing the result of the preceding patches.

root_inherited.gif show the page reached by the "config" command with no 
option.  Here, I scrolled down to a setting that is inherited from 
net1.nvo, to show the 'inherited' note that appears for settings not set 
directly in local scope.

smbios_readonly.gif shows the page reached by "config smbios" or by 
navigating there from the root page.  The "read only" alert appears 
because I (deliberately) tried to edit one of the read-only smbios settings.

nvo_parent.gif shows the page reached by "config net1.nvo" or by 
navigating there in the hierarchy browser.  The instructions at the 
bottom specify that "Enter" will take one to the parent page.  The 
highlighted options are set at this level of the hierarchy. 
Non-highlighted values contain defaults.  (At higher levels, the gpxe 
default is to inherit any value set in a child.)  The intent of this 
highlighting -- and the 'inherited' message mentioned above -- is to 
make gPXE's name space semantics a bit less confusing.
