busybox, as build by genkernel, doesn't support the -R option to udhcpc. I'll attach a patch here shortly. On a side note, I have gotten unionfs working with 2.6.22 and genkernel. But since I had to patch the kernel manually (unionfs doesn't support external modules any more), I don't see these changes making it in anytime soon. If someone is interested, contact me. Reproducible: Always Steps to Reproduce:
Created attachment 137650 [details, diff] udhcpc patch Note that this patch merely remove the usage of -R (because I don't need it).
