Description Pete Zaitcev 2002-08-22 00:03:56 UTC 
Description of Problem:

Certain daemons forget to close their descriptors.
The initlog (process.c) closes stderr and stdout but
forgets stdin. Thus, login sessions fail to exist if
/sbin/service was executed.

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

initscripts-6.43-1

How Reproducible:

100%

Steps to Reproduce:
1. Log into a remote server, not running NFS by default.
2. Type "service nfs start"
3. Try to log out

Actual Results:

Login session hangs due to attached stdin in a daemon.

Expected Results:

Login sessions ending normally.

Additional Information:
	
The code around process.c:runCommand() is not maintainable.
Comment 1 Pete Zaitcev 2002-08-22 00:14:25 UTC 
This can be worked around with a simple patch to the script,
but it seems proper to fix the problem in initlog, in order
to avoid surprises in the future.

Comment 2 Bill Nottingham 2005-09-29 20:15:46 UTC 
Closing bugs on older, no longer supported, releases. Apologies for any lack of
response.
Realistically, daemons should be fixed.
