This appears to be due to openssl requests blocking or failing until sufficient entropy is available for random number generation.

The target device is based on the TI AM335X (Sitara) ARM Cortex A8 SOC. The SOC (system on a chip) has a hardware random number generator, which requires a kernel driver to be built.

Though the kernel driver was being loaded, that's not enough for the hardware RNG to be used by the OS.

After installing the rng-tools package, which connects the hardware RNG / kernel driver to the OS layer, entropy at boot went up 100-fold; and nginx started normally at boot.
