I looked at it briefly, and I see that we don’t have n/w enabled and this kernel is sort of crippled if
we don’t have  /proc/sys/ can you enable CONFIG_PROC_SYSCTL and see how much size it increased. Because
this would pave way to enable busybox-mdev for device management among other things you could do
with sysctls
