Description Sammy 2004-08-19 10:41:36 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (compatible; Konqueror/3.2; Linux; X11; en_US, en_US.UTF-8, en) (KHTML, like Gecko)

Description of problem:
During boot rc.sysinit calls rngd which produces an error stating that
hw_random cannot be found. Should there be a file /etc/rc.d/init.d/random?
This is mentioned in /etc/readahead.early.files! If hw_random module
is started there is no error.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.install kernel-utils-2.4-12.1.142

This will get created by udev in the near future.
Comment 3 Bill Nottingham 2004-08-20 00:29:06 EDT
A check for the device node is in initscripts-7.64-1.
Comment 4 David Lehman 2005-02-04 17:45:46 EST
The check will never succeed AFAICT, because it checks for a regular
file, not a character device.
Comment 7 H. Peter Anvin 2005-09-28 14:22:12 EDT
In current rc.sysinit, this test is:

#[ -x /sbin/rngd -a -c /dev/hw_random ] && rngd

... which looks correct, except for the fact that it's commented out!  This is a
major loss for a hwrng-equipped server.
Comment 8 Bill Nottingham 2005-09-28 15:16:26 EDT
rngd hangs if the hw_random device exists (the module is loaded) but there isn't
any specific hw RNG backend. Behavior like that isn't really appropriate in
rc.sysinit. :)
