how to change mount option using fdi ?

I'm using SuSE 10.1. Does anyone know how to add mount options with fdi file? I want to update the mount option for my USB flash. I add a new fdi and set as follow, but it simply doesn't work even if I can see the value in "lshal". <?xml version="1.0" encoding="ISO-8859-1"?> <deviceinfo version="0.2"> <device> <match key="storage.bus" string="usb"> <merge key="storage.policy.mount_option.uid=1002" type="bool">true</merge> <merge key="storage.policy.mount_option.umask=077" type="bool">true</merge> </match> </device> </deviceinfo> Jason
