Да когда же это закончится ...

Очередное падение и флуд в syslog :

Тут в недавней теме винили во всех бедах entware и предлагали проверить наличие проблем без него. Только вот какая заковыка - сейчас syslog пишется в файл силами того самого entware. Так что если я от него откажусь, у меня не будет возможности снимать syslog в режиме 24/7. При возникновении проблем /ci/log.txt тупо не отдаётся и его загрузка уходит в loop. Посему у меня вопрос - что делать ?

Ну и до кучи пожелание - неплохо было бы иметь возможность писать системный лог на накопитель силами самого роутера.
