Yeah, a symlink is impossible to update atomically (on most platforms
anyway).  Plain file containing the pathname seems better.

Another point is that we might not necessarily want *only* the pathname in
there. has accreted more stuff over time, and this file
might too.  I can see wanting the syslogger PID in there, for example,
so that onlookers can detect a totally stale file.  (Not proposing this
right now, just pointing out that it's a conceivable future feature.)
