Oh, you already know about the problem with NFS. I asked our kernel
guys and they said there's no way to get the block size of the
remote system and that I should implement some max block size value
like 4096.
The block size IMHO only matters for "rounding up" file sizes, assuming
a file always needs one block. This is not true for some file systems
like reiserfs, so it's kind of questionable anyways.

AFAIK it (currently) can't be different on a linux system. But maybe
someone wants to use rpm on some other OS where it makes a difference.

I'll create a patch for the "max block size".
