In the alternate, the only reason this happened now is because we are
finally having the Debian packages follow where upstream has decided to
put the files. Having different packages moving files around to
different places only increases user confusion, and creates 'only on
For example, a significant number of issues came about as folks tried to
divine if a particular TDB was short, medium or long-term, when no such
separation existed in the code.
We (upstream) have gone to significant effort to integrate the FHS
changes that have been proposed via Debian, I can only ask that having
got to a mutually agreed state, that Debian not change it again, having
once more Debian packages special and different.
Or in the alternate, propose such changes upstream.
