FWIW, FHS states[1]:
"The following files, or symbolic links to files, must be in /var/log,
if the corresponding subsystem is installed:
File Description
lastlog record of last login of each user
messages system messages from syslogd"
There is clearly some ambiguity there; I'm not sure FHS writers
considered the possibility of something that is clearly meant to fulfill
the role of a system logging daemon but which does not want to
write /var/log/messages .
