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):
Steps to Reproduce:
*** Bug 130368 has been marked as a duplicate of this bug. ***
This will get created by udev in the near future.
A check for the device node is in initscripts-7.64-1.
The check will never succeed AFAICT, because it checks for a regular
file, not a character device.
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.
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
Just a note: see bug #215371 for related discussion.
