I'm running 6.1-STABLE on an AMD64 current as of a few minutes ago,
and I've booted single user and done a fsck on the filesystems.

I'm running the following commands:

	# mksnap_ffs /home /home/.snap/snapshot

then

	# fsck_ffs /home/.snap/snapshot

and I get the following errors:

** /home/.snap/snapshot (NO WRITE)

Othertimes when I run the same commands, I get a consistent snapshot.

Am I doing something wrong?

Thanks,
