Hmm, my reading of this has been that programs should default to using a
directory in /srv (it says "should be used as the default location for
such data"), but have to allow being configured to use any other
directory in or out of /srv for thier data. Also that if program A is
looking for program B's data, it cannot just assume that it's in some
default location in /srv.

So, for example, some of the tftp daemons in Debian have been configured
to default to using /srv/tftpboot; they still have to be configurable to
use other paths like /var/lib/tftpboot or /srv/intranet/tftpboot. And a
program like the new di-netboot-assistant can't assume that /srv/tftpboot
is the right place to dump files -- but it could ask with that as a
default.

I think that there's room for Debian to establish distro-wide policies
for the *default* directories in /srv, as a suppliment to the FHS.
