Impact: A regression in the hal-->devicekit-disks transition resulted in hidden recovery partitions appearing after an upgrade to 9.10. Some ACER systems use a hidden recovery partition of type 0x12 (label 'PQSERVICE'). These hidden partitions were hidden from the user in 9.04, but are not properly hidden in 9.10 with devicekit-disks 007-2ubuntu3. In 9.10 it is possible for the user to mount these hidden partitions and modify the files on them, inadvertently breaking the system recovery feature.
Fix: The patch 03-hide-configuration-partition-12.patch fixes this behavior on 9.10. TEST CASE: On a system that contains a hidden partition of type 0x12, install 9.04. Notice that the partition cannot be accessed from the file manager or the Places menu. Upgrade to 9.10; the hidden partition will now be visible in the file manager. Update to a patched version of devicekit-disks. The hidden partition should not be accessible from the file manager or Places menu. Regression potential: Users who rely on access to a hidden partition of type 0x12 will no longer have access to the partition. I expect this is a very small set of users. -- Partition type 0x12 could be hidden https://bugs.launchpad.net/bugs/451304 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
