RAC,Linux -- asm libraries , Do we need to install asmlib, ASM kernel driver and ASM support in OEL6?

Normally, there are 3 packages which need to be installed in Linux environment that will run Oracle ASM.
These packages are;

oracleasm (The kernel driver)
oracleasmlib (ASM libraries)
oracleasm-support  (ASM Support scripts)

We normally install these one by one, and use our ASM instances in our RAC environment accordingly.
On the other hand; I have realized that the things are a little different, when you use Oracle Enterprise Linux 6 for your RAC environment.
There are 3 facts for a RAC installation based on an Oracle Enterprise Linux 6)

1)The oracleasm kernel driver is built into the Unbreakable Enterprise Kernel for Oracle Linux 6 and does not need to be installed manually.
2)oracleasm-support can be choosed while installing Oracle Linux 6, so we do not need to install it manually.
But if we want to install it manually; the oracleasm-support package can be downloaded from the Unbreakable Linux Network(ULN) if you have an active support subscription, or from http://public-yum.oracle.com if you do not.
3) The oracleasmlib packages still need to be installed manually, it can be downloaded from  "http://www.oracle.com/technetwork/server-storage/linux/asmlib/ol6-1709075.html" ->
