 Posted: Sat Dec 06, 2008 12:23 pm Post subject: GNOME: too much automounting |
 |
|
| In GNOME 2.24, my Windows partition gets automounted (it is not in /etc/fstab). How do I prevent automounting of that partition, without losing the ability of having my other devices (mostly USB sticks and drives) automounted? |

Hi,
HAL stuff :
| Code: |
$ cat /etc/hal/fdi/policy/99-personal-rules.fdi
<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
<!-- Auto-mount only removable media -->
<device>
<match key="storage.hotpluggable" bool="false">
<match key="storage.removable" bool="false">
<merge key="storage.automount_enabled_hint" type="bool">false</merge>
</match>
</match>
</device>
</deviceinfo>

| Thanks, that worked. So what I saw was normal default behavior? |

Yes. Default configuration of hal : if something is mountable but not mounted and not defined in /etc/fstab, then flag automount = true.
gnome-mount read HAL informations at login, and do it's job accordingly. |

Thanks a lot!
Is there also a way to prevent a specific USB-Device from automounting?
I use pam_usb and don't want the USB-Stick containing my auth-code to be mounted everytime it is plugged in, but all other USB-Devices to act "normally".

Yes, easy. When you plugged-in your usb-stick, the kernel gives a name for the device, for example /dev/sdd. You can get it with dmesg.
Then you can run the following command to get HAL informations (here is relevant informations for my usb stick) :
| Quote: |
$ hal-device $(hal-find-by-property --key block.device --string /dev/sdd)
udi = '/org/freedesktop/Hal/devices/storage_serial_ChipsBnk_Flash_Disk_0_0'
storage.firmware_version = '2.00' (string)
storage.lun = 0 (0x0) (int)
storage.removable.media_size = 1046609408 (0x3e61fe00) (uint64)
info.vendor = 'ChipsBnk' (string)
storage.partitioning_scheme = 'mbr' (string)
info.addons = { 'hald-addon-storage' } (string list)
linux.hotplug_type = 3 (0x3) (int)
info.product = 'Flash Disk' (string)
info.udi = '/org/freedesktop/Hal/devices/storage_serial_ChipsBnk_Flash_Disk_0_0' (string)
block.device = '/dev/sdd' (string)
block.major = 8 (0x8) (int)
info.interfaces = { 'org.freedesktop.Hal.Device.Storage.Removable' } (string list)
block.minor = 48 (0x30) (int)
block.is_volume = false (bool)
storage.bus = 'usb' (string)
storage.no_partitions_hint = false (bool)
storage.media_check_enabled = true (bool)
info.category = 'storage' (string)
info.capabilities = { 'storage', 'block' } (string list)
storage.automount_enabled_hint = true (bool)
storage.model = 'Flash Disk' (string)
storage.vendor = 'ChipsBnk' (string)
storage.drive_type = 'disk' (string)
storage.originating_device = '/org/freedesktop/Hal/devices/usb_device_204_6025_noserial_if0' (string)
storage.removable = true (bool)
storage.removable.media_available = true (bool)
storage.hotpluggable = true (bool)
linux.sysfs_path = '/sys/block/sdd' (string)
storage.requires_eject = false (bool)
info.parent = '/org/freedesktop/Hal/devices/usb_device_204_6025_noserial_if0_scsi_host_scsi_device_lun0' (string)
storage.removable.support_async_notification = false (bool)
storage.size = 0 (0x0) (uint64)
block.storage_device = '/org/freedesktop/Hal/devices/storage_serial_ChipsBnk_Flash_Disk_0_0' (string)
storage.serial = 'ChipsBnk_Flash_Disk-0:0' (string)
|
Using these informations, you should be able to write rules for a specific device, using for example the storage.serial string :
| Quote: |
<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
<!-- Rule for a specific usb stick -->
<device>
<match key="storage.hotpluggable" bool="true">
<match key="storage.removable" bool="true">
<match key="storage.serial" string="ChipsBnk_Flash_Disk-0:0">
<merge key="storage.automount_enabled_hint" type="bool">false</merge>
</match>
</match>
</match>
</device>
</deviceinfo>
|
This rule means : if the device is hotpluggable, and is removable, and it's serial string match 'ChipsBnk_Flash_Disk-0:0', then flag automount = false.
Should work, untested. Everything is here : http://people.freedesktop.org/~david/hal-spec/hal-spec.html |

That's it! Thanks a lot!
I tried to match for volume.uuid, which failed - matching the entire device was the clue

You probably can do it using indirections, something like this :
| Code: |
<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
<!-- Rule for a specific usb stick -->
<device>
<match key="volume.uuid" string="e4191178-6ab3-4998-b06a-1097288442c1">
<merge key="@info.parent:storage.automount_enabled_hint" type="bool">false</merge>
</match>
</device>
</deviceinfo>
|
This should work, but again, untested.
The volume.uuid string is associated to the partition on the device, not to the device itself, but the automount flag is associated to the device, not to the partition. |
