Hello,

Upgraded to stable/13-n253992-3ececb0f35b9 (amd64) just now and saw an
error I've not seen before, on bootup

####### snip

Starting unbound.
Clearing /tmp.
Creating and/or trimming log files.
eval: startmsg: not found
eval: startmsg: not found
Updating motd:.
Updating /var/run/os-release done.
Starting syslogd.

####### snip

What is "eval: startmsg: not found" pertaining to?

It seems harmless, but it's new, and am asking here because I'm
wondering if it's something from -current? (am not using -current)
