I believe ./run and ./log/run are started simultaneously, so svlogd may
run before mkdir or between mkdir and chown. I'm not sure this may result
in having no logger at all as you explained because if svlogd fail it
should be restarted. Anyway, I think you should move mkdir from ./run to

Also it doesn't clear why you change owner of log directory to "user1" -
usually log directory is owned by user "log" (and svlogd run as user
"log") while your service run using some other user (this suppose you
didn't try to access log directory from your application).

So, maybe you should try this:

--- ./run:
cd /opt/baz/current
exec chpst -u user1 ./run_baz 2>&1

--- ./log/run:
mkdir -p /mnt/log/baz
chown -R log /mnt/log/baz
exec chpst -u log svlogd -ttt /mnt/log/baz/
