Yes, that's it. Ive tried it here myself, and indeed this behaviour.
The polling is started also with a command like udisks --enumerate
Thus the way to enable polling for all removable devices is to start at
udisks --enumerate >> /dev/null ?
in some init script.
Futher what's the mount options for? I've seen already that it mounts at
/media. Can I tell it where to mount?
And how are the default options determined??
I'm specially interested cause I'm building system which provides users
easy, powerfull en intuitive access to all kinds of resources, also USB
disks, CDroms and Harddisk.
It's build with a FUSE module fuse-workspace-ll, the automounter
autofs, ConsoleKit for sessionsupport, udev and udisks (or HAL) for
hardware detection, cifs for mounting SMB shares and a lot of scripts.
especially the page
for the latest screenshots,
It's not using udisks now for the mounting, but just the direct commands
for it like mount -t ext4 ...
and some default options and options to make the user for which the
device is mounted "owner" of the device.
It supports MultiSeat, it's possible that a device is mounted multiple
times, for different users.
Does udisks supports more than one mountpoint?
