Since I have this blog I guess I should put something here so.
After reading about the kernel summit on lwn, there are 2 things I miss that I have heard little about lately. Online resize of ext2/3, I have done this, on my desktop, using xfs for a while. And it's nice to be able to resize the filesystem just as easy as you resize the lvm volume. Now xfs was merged in 2.5 but ext2/3 rezise patches is not. I hope it will be soon.
