Hi!

Вот что-то такое должно быть. Как мимимум. Что из того, что может не
работать:

- не проверяется конфликтность lsm между собой (т.е. если написать в
  /etc/lsm/modules и realtime и trustees и/или capability, что-то одно не
  загрузится). Впрочем, это сложно проверить, а тому, кто знает, это не
  надо.

Что работает:

- все подгружаемые модули хранятся в файле /etc/lsm/modules, в виде
  списка, идентичного /etc/modules

- можно указывать опции для загрузки lsm a la /etc/modules типа 
  <module> [param], где [param] - необязательный параметр.

- по-умолчанию, если /etc/lsm/modules не существует, грузится
  "умолчательный" lsm - это capability.

PS Если мантейнер startup не против, могу повесить это в bugzilla.
