Better error message for copying to read-only folder

[Kev]

On hrev46164, I see that /boot/common/bin is now read-only. However, I was a bit confused at first when I tried to copy a file to it, because the error message implied it wasn't just the folder, but the whole volume: "You can't move or copy items to read-only volumes."

The error message is actually correct: /boot/system, /boot/common and /boot/home/config are now packagefs mount points, and the packagefs is a read-only filesystem. The only exception is certain folders such as /packages and /non-packaged which it allows to "shine through" from the underlying BFS. As such, when Tracker gets the copy error back from the OS, it is in fact told that a copy to a read-only FS was attempted, and not just a folder.

It'd take a bit of work to specially handle that in the case of a packagefs volume.

Oh, I had no idea. Well, that makes sense. Thanks for the explanation :)

Moving Tracker enhancement tickets out of R1 milestone -- Tracker's source code comes from BeOS R5, so it already has all the features it did on R5.
