Description Doug Henderson 2005-05-09 11:21:36 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.7) Gecko/20050414 Firefox/1.0.3

Description of problem:
boot fully updated system with build 1287.
modify grub parameters to add "selinux=0"

issue telinit 5 as root
startup my usual suite of apps (Oracle 10g, seti@home)

connected remotely via ssh.

$ /sbin/shutdown -r now
shutdown: you must be root to do that!

[doug@lambda ~]$ /sbin/reboot
reboot: must be superuser.

$ reboot
*** system reboots. ***
man page for reboot says non-root user will get diagnostic message.

# which reboot

$ ls -li /usr/bin/reboot /sbin/reboot
4128951 lrwxrwxrwx  1 root root  4 Apr 28 06:22 /sbin/reboot -> halt
5903240 lrwxrwxrwx  1 root root 13 Apr 11 22:51 /usr/bin/reboot -> consolehelper

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

How reproducible:

Steps to Reproduce:

Additional info:
Comment 1 Doug Henderson 2005-05-09 11:22:44 EDT
changed component from SysVinit to usermode as it is /usr/bin/reboot not
/sbin/reboot that causes problem.
Comment 2 Bill Nottingham 2005-05-09 14:43:53 EDT
If you're logged in on the console (this includes X), this is expected behavior.
