In http.debian.org, softlinks are used to pair stable with sarge,
testing with etch, and unstable with sid. The last time I looked (at
least a few months ago) unstable was the real directory and sid was
the softlink. Today, it is the other way around: Sid is real directory
and unstable is a softlink. It appears that some day soon all the
nasty complication of which I have been warning will be gone. There is
still a complication that may reach out and bite someone: the header
of the file named Release, for sarge contains two lines,
> Suite: stable
and
> Codename: sarge
These two lines are consistent now, but will be inconsistent when etch
becomes stable. Maybe this will be gone soon, too.
