I am curious to know how easy it is (or not) to have the newish
Advanced format  support in Debian-installer , as well as the
ext* filesystems . I remember a story about it which came in
osnews long-time back (around 1.5 years +) but do not really know
how relevant they are or not atm. I am asking as from what i read
alongwith the above at the very least the perception is most of the
changes being done are to take care of growth for the next 20 + years.
I also saw discussions on the linux kernel page  but that wiki
page is not current with the linux 3.x kernels. I did however spot an
article on lwn.net  .
Sadly there is no wiki entry about 'Advanced Format' on the Debian
wiki. It would be nice if somebody has some updated instructions for
