Description Xiaomei Gao 2012-07-16 09:48:00 EDT
Description of problem:

'shutdown -a/-f/-g/-n/-q/-v now' with these options all make guest into 

single user mode, but "man shutdown" has no these options.  

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

#rpm -qf `which shutdown`


How reproducible:


Steps to Reproduce:

1. # shutdown -n now
   The system is going down for maintenance NOW!

2. # runlevel 
     1 S

3. man shutdown
Actual results:

host/huest goes into single mode

Expected results:

should prompt info: shutdown: invalid option -- 'n'

Thanks for the report, there should be probably some check for args. I will discuss this with upstream.
Comment 3 Lukáš Nykrýn 2012-07-24 07:37:32 EDT
This behavior is actually the same as in sysvinit. Maybe it would be better just to mention it in manpage. Again I will discuss this with upstream.
Comment 4 RHEL Product and Program Management 2012-09-07 01:10:51 EDT
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unable to address this
request at this time.

Red Hat invites you to ask your support representative to
propose this request, if appropriate, in the next release of
Red Hat Enterprise Linux.
Comment 6 Lukáš Nykrýn 2015-10-13 08:55:04 EDT
This behavior is because of backward compatibility.
