useradd used with no home directory still shows home dir in passwd file

[marko]

I added a clamav user via these commands (Fedora 9 64bit)

groupadd clamav
useradd -g clamav -s /sbin/nologin -c "Clam Antivirus" -M clamav

as far as I know, this should make a clamav user, that has no password, can not get to a shell
(shell is /sbin/nologin) and has no home directory (-M , forces no home dir to be made)

The /home directory is correctly void of a 'clamav' directory but when I run finger clamav I still see that
/home/clamav is quoted as it's home. Also /etc/passwd has this:

clamav:x:501:504lam Antivirus:/home/clamav:/sbin/nologin


shouldn't where that (red) directory is be empty like this:

clamav:x:501:504lam Antivirus::/sbin/nologin

?
