Is it possible to add a menu entry to the PXE menu that would generate a
command to image a workstation. For example,

I can manually type this command at the bash# prompt to image a
workstation:

img restorep x.x.x.x //path_to_image/somehwere/...

But it would be nice to be able to add an entry to the PXE menu that would
perform this task just by selecting the menu option. Is it possible to
modify the menu and add such entry?

Thanks
