Problem with Current amd64

[Filippo Moretti]

I installed from the latest snapshot,made buildworld with custom kernel,installed bash and mc from ports.It was the first time I used zfs on 1 Tb sata III disk.When I rebooted the system I got a nasty surprise:my home directory,ports and src are no longer there.This never happened to me.Should I reinstall or any other suggestion really appreciated
Sincerely
Filippo
