How about
SERVICE_NAME=$(basename $(dirname $(readlink -f .)))
Of course, I don't know how portable readlink is.

You're right, but at least "cd $LOGDIR || exit 1" fails in a predictable

chown -R is recursive, meaning that it will chown the svlogd 'config' file
which resides in the logdir to the user svlogd will run as.
I agree this only has theoretical significance.
