But what _exactly_ does it do?
Is there a way to leverage any knowledge of erase block size at file
system creation time?
Are there any special parameters that might affect locations of
superblocks and metadata?
Is there a way to ensure they don't span erase block boundaries?
What about ATA TRIM command support? Is this available? Is it included
in the version in Fedora 13?
