Q: u-root dhcp client take ages, what is the problem ?

A: the problem is a lack of early entropy:

  1. If your platform has a hwrng enable it with CONFIG_ARCH_RANDOM and trust it with CONFIG_RANDOM_TRUST_CPU.
  2. If your platform don’t have hwrng, add uroot.nohwrng to your kernel command line so u-root use a non-blocking random implementation.
