> On my machine portmap is started/running anyhow, also if no nfs share has been mounted ever. In Lucid I have just installed 'nfs-common' (not the kernel server!). It is only used when I temporarely mount some nfs3-exports from guests in VBox, or nfs4-exports from my nas (running Lenny-armel).

Yes, statd stops and starts with portmap...

from statd.conf:

start on (started portmap ON_BOOT=
          or (local-filesystems and started portmap ON_BOOT=y))
stop on stopping portmap

This is bug #531912, which is awaiting review. The init.d script is only
retained for chroots. Use 'service ssh stop' until that bug is fixed.
