It is a laptop, I was rebooting to connect a firewire CD-RW and dump my
partition onto a CD-R.

In fact, the problem occured this way I think :
1) I upgraded both kernel and NVidia drivers, hum upgrade time to do a dump,
2) I rebooted
3) The mount /home failed
4) self.stupidity++ : I typed mkfs.xfs when I was thinking of fsck.xfs
