关于UPDATE mkinitrd的问题，我都快疯了。

上网查得mkinitrd依懒于device-mapper,而device-mapper又依懒于lvm2.但我在安装lvm2时碰到了这个：
[root@localhost root]# rpm -Uvh lvm2-2.01.14-4.i386.rpm
error: Failed dependencies:
        device-mapper >= 1.01.03 is needed by lvm2-2.01.14-4

在安装readline时碰到这个：
[root@localhost root]# rpm -Uvh readline-5.0-3.i386.rpm
warning: readline-5.0-3.i386.rpm: V3 DSA signature: NOKEY, key ID 4f2a6fd2

        readline = 4.3 is needed by (installed) readline-devel-4.3-5

在安装libselinux又碰到这个：
[root@localhost root]# rpm -Uvh libselinux-1.23.10-2.i386.rpm
warning: libselinux-1.23.10-2.i386.rpm: V3 DSA signature: NOKEY, key ID 4f2a6fd2

怎么解决这些问题呀。
