Canonical way to upgrade an existing nfsroot?

[Steffen Grunewald]

Apparently I have killed a working nfsroot by naively running "apt-get upgrade".
What's the canonical way to keep a nfsroot updated? Would it be sufficient
to "hold" the dracut* packages so their postinst scripts don't fail?

Thanks,
 S
