uss is old and kas-encumbered and I don't think it gets much attention
anymore. When discussing the list of features to keep and drop for 2.0,
uss was considered to be removed from the project entirely, until it was
brought up that someone actually uses it without using it with kaserver.
So it is used, but it's susceptible to bitrot, and so I'm not surprised
that it's not packaged.
Also, I presume you saw references to uss in the admin guide? The admin
guide contains a lot of old information, I believe.

The code to emit mariner notices still exists, but we don't have the
traditional tool to capture them and log them usefully (see the manpage
for 'fs monitor/mariner'
<http://docs.openafs.org/Reference/1/fs_monitor.html>). There is
something to process them on Mac OS X specifically, but that's it as far
as I know.
You may want to look at 'fstrace'. It's a lot less useful than what it
sounds like you want, and you kinda have to know how to interpret the
output, but if you're trying to debug client operations, it is useful. A
quick how-to on how to get it to produce output was written by Simon:
Also, server disconnection/reconnection notices should be logged in
syslog without you needing to do anything.
