ports/136676: hald/GNOME (I guess) (re) mounted /usr and /var through their /dev/ufsid devices

[Andrew Reilly]

I suspect that these messages in dmesg are probably significant:
ad6: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=40<UNCORRECTABLE> LBA=201485471
GEOM_MIRROR: Request failed (error=5).  ad6[READ(offset=103160561152, length=16384)]
GEOM_MIRROR: Device gm0: provider ad6 disconnected.

So, I have a dud drive?  That's a bit disappointing: it's only
new.

But why would hald mount it if gmirror doesn't like it?

I'll have to try rebooting the system...
