I am working on a system that I did not create the BusyBox build for. I do not want to recompile BusyBox for fear that my configuration will not completely match the original and besides this the system is functioning well enough on this build. I could be swayed to do this if I knew of a way to pull the configuration of a running BusyBox install much like a running kernel.I am trying to figure out how to disable the switches used to call udhcpc from the ifup command. I can see the defaults compiled into the build that I am using. They are -R -n -p. I want for this process to fork into the background and I thought using udhcpc_opts -b in /etc/networking/interfaces would solve this issue. I get the fork to the background and then the process kills. If i just call udhcpc -b it forks to the background indefinitely.Is there a way to override the -n switch through something I can put into udhcpc_opts? Thank you.
