Description of problem:
When I start /etc/init.d/autofs it hangs forever.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot a headless system with no keyboard or mouse and with / as tmpfs
2. Start /etc/init.d/autofs start
Autofs should have started and bash should have returned to the prompt.
I'm not sure if the fact that the system is headless or that / is tmpfs is relevant.
However, as reported in http://firstname.lastname@example.org/msg06460.html, replacing /dev/random with a symlink to /dev/urandom fixes the problem.
I haven't checked into this yet, thanks for the reminder.

I am running into this as well. I believe the hangs are caused by the
calls to seed_random() which in turn tries to read /dev/random and
that hangs on entropy starved systems. Changing Patch66:
autofs-5.0.1-rc3-random-selection.patch to use /dev/urandom instead of
/dev/random is the easy fix. /dev/random is an overkill for this
