>Description:
	I was upgrading the kernel on my alpha the other day (mv
/netbsd /onetbsd; cp netbsd /), and when I rebooted, the kernel
panicked while shutting down: panic: insmntque into dying filesystem

Stack trace shows:
panic+0xe8
insmntque+0x4
getnewvnode+0x334
union_allocvp+0x454
union_root+0xf4
union_unmount+0x38
dounmount+0x15c
vfs_unmountall+0x7c
vfs_shutdown+0x240
cpu_reboot+0x68
sys_reboot+0x7c
syscall+0x140

The relevant filesystems seem to be:
/dev/sd0d on /usr type ffs (NFS exported, local, soft dependencies)
<below>:/usr/src on /usr/src.local type union

>How-To-Repeat:
	Unknown; it doesn't seem to happen every time.
