CentOS - Jan 2009 - ext4 in 5.3

Hi guys - I'm really looking forward to 5.3 for the potential of ext4.
I am moving/copying image files lately 8G file and it is slow. I am 
hoping that ext4 really speeds that up.

My question is: will we be able to boot ext4 file systems?
Will the boot partition still be ext3 and then have to mount the ext4 
filesystem?
I did not see mention of it in the release notes.

Thanks,

Jerry

Yes, but you wouldn't gain much by making /boot ext4.

I don't think it will speed things up much. 8GB files are mostly
hardware throughput and ext3/4 will actually be slower because the
journalling etc are to make it more robust but at a speed cost. You
would probably see better speed by going to ext2.

Well looking at this I would say yes...
