i did something like this:

m=$(%addusertogroup http blah)
if [ -n "$m" ]; then
    echo >&2 "$m"
    if [ -f /var/lock/subsys/apache ]; then
        /etc/rc.d/init.d/apache restart 1>&2
    fi
    if [ -f /var/lock/subsys/httpd ]; then
        /etc/rc.d/init.d/httpd restart 1>&2
    fi                                                                                                                         
fi 

but this doesn't look cool at all

and changing %addusertogroup to return something else than true, i don't want 
to do, it would break existing packages. altho mass commit on them is also an 
answer.
