Disabling LVM check/startup on FC2

[Optimized]

Hello,

My FC2 system is installed on linux raid volume but I have no use for
LVM.

I would like to disable the lvm check on system startup since it always
fails, how should I proceed in order to make it clean?

I thought about commenting (#) the following section of the
/etc/rc.sysinit file :

...
# LVM2 initialization
if [ -x /sbin/lvm.static ]; then
    if ! LC_ALL=C fgrep -q "device-mapper" /proc/devices 2>/dev/null ;
then
	modprobe dm-mod >/dev/null 2>&1
    fi
    /bin/rm -f /dev/mapper/control
    echo "mkdmnod" | /sbin/nash --quiet >/dev/null 2>&1
    [ -n "$SELINUX" ] && restorecon /dev/mapper/control
    if [ -c /dev/mapper/control -a -x /sbin/lvm.static ]; then
	if /sbin/lvm.static vgscan > /dev/null 2>&1 ; then
	    action $"Setting up Logical Volume Management:" /sbin/lvm.static
vgchange -a y && /sbin/lvm vgmknodes
	fi
    fi
fi
# LVM initialization
if [ -f /etc/lvmtab ]; then
    [ -e /proc/lvm ] || modprobe lvm-mod > /dev/null 2>&1
    if [ -e /proc/lvm -a -x /sbin/vgchange ]; then
	action $"Setting up Logical Volume Management:" /sbin/vgscan &&
/sbin/vgchange -a y
    fi
fi

# Start up swapping.
...

But maybe there is a better way to do so?

Many thanks for your time and help
