#3026 assigned bug

Removable Media: Ejecting a CD leaves ghost of mount point

Mounting a CD or DVD then pressing the eject button to remove it properly removes the entry from Tracker, but according to the 'ls' command in Terminal, the entry remains.

When re-inserting the disc, a new folder in the root filesystem node is created with the same name and an incrementing number. This is entirely reproducible (on real hardware at the very least).

Unmounting the volume with Tracker avoids this problem and ejects the CD happily.

Perhaps there's an issue with a lock on the folder when the system detects the CD is removed? I'm unable to test this with USB media.

There doesn't seem to be a locking problem, it's just that unmounting a device by default does not remove the directory where it was mounted. The same happen if you use the unmount command.

The code taking care of cleaning up when unmounting is in BPartition. It does this by leaving a "marker" in the created directory, this is an empty dir named _HaikuAutoCreated. Maybe this should be moved to the lower level (fs_mount_volume/fs_unmount_volume), or maybe the unmount command and the auto-unmount on eject should use BPartition instead.

Dunno how I missed this.. Somewhat benign but still part of the big picture. Can an admin please "Cc" me, I'd like to have this ticket in my query list, thank you.
