>Release:        2.9
>Environment:
	System      : OpenBSD 2.9
	Architecture: OpenBSD.alpha
	Machine     : alpha
>Description:
	If you use chsh on an ordinary user, to, say, switch shells,
	a long listing of the root dir will print "0" in the user
	column instead of "root".
>How-To-Repeat:
	suxrox% uname -a
	OpenBSD suxrox 2.9 GENERIC#33 alpha
	suxrox% ls -l /bsd
	-rw-r--r--  1 root  wheel  5115787 Jun  6 12:15 /bsd
	suxrox% chsh -s /bin/csh
	suxrox% ls -l /bsd
	-rw-r--r--  1 0  wheel  5115787 Jun  6 12:15 /bsd
	suxrox% 
>Fix:
	Sorry, my disk w/ source has croaked, so I don't have a fix.
	Once the 0 -> root mapping is busted, though, it can be
	restored using vipw.
