I'm not sure. I think if this happens on a non-removable hard drive, a
panic is the rigth thing to do. You'll get a core dump, and it's not
necesserely a good thing to let a server operate without all it's filesystems.
On my shell server, if /var gets corrupted, I'm sure I prefer to get a panic
instead of letting it run without accounting.
