Well that took all of 90 seconds...
In rc.d/random we have:
extra_commands="saveseed"
saveseed_cmd="${name}_stop"
and in rc.d/postrandom we have:
postrandom_start()
{
/etc/rc.d/random fastsaveseed
...
and so it tries to write an entropy file at startup and hangs,
presumably because /dev/random hasn't been sufficiently fed to generate
that much random output?
