While reading about NILFS here:

I saw this:
One of the most noticeable features of NILFS is that it can
"continuously and automatically save instantaneous states of the
file system without interrupting service". NILFS refers to these as
checkpoints. In contrast, other file systems such as ZFS, can
provide snapshots but they have to suspend operation to perform the
snapshot operation. NILFS doesn’t have to do this. The snapshots
(checkpoints) are part of the file system design itself.
I don't think that's correct. Can someone clarify?
It sounds to me like they confused Solaris UFS with ZFS. What they
say applies to UFS, but not ZFS.
