Попробовал поработать с ivman и нарвался на странность - флеша не
монтируется сама.
Содержимое /etc/ivman/IvmConfigActions.xml :
<?xml version="1.0" encoding="UTF-8" ?>

С закоментированным блоком Match действия не выполняются вообще. Ниже
приведу вывод lshal по поводу флеши.

Файлы IvmConfigConditions.xml и IvmConfigProperties.xml я не трогал.

Ясно видно что один из блоков про флеш вообще, а второй про раздел на
этой влеше. Выше я приводил пример про hal.block.is_volume который
отчегото не срабатывает.
В результате втыкания влешки действия exec и execun отрабатывают, но
флеш не монтируется. Но самое странное случилось когда я попытался
заглянуть в дэбаг ivman командой ?ivman -d?. Среди прочего команда вывела:
...

IvmConfig/IvmConfigCommon.c:177 (ivm_device_is_mountable) Device
/dev/sdb can't be mounted because it is not a volume
... и т.д.
При этом второй раз срабатывает команда exec и флешка таки монтируется в
/media/sdb1.
Как такую ситуацию правильно разруливать?
