Есть машина с jailaми, которые админятся через ezjail в который прикручен сетевой стек. Конфиг выглядет так.

Как видите "/bin/sh /etc/rc" стартует в секции poststart, а в start закомментирован, это нужно для того чтобы «rc» подгрузился после сетевого стека.
Так вот получается, что после старта jail стартует "/bin/sh /etc/rc" и некоторые процессы запускаются дважды. Выглядет это так:

Как видно mpd и cron запущен дважды. Если смотреть /var/run/mpd.pid увидем 3310.
Никак не пойму что не так, и как rc то два раза стартует?
