No. The kernel log (kern.* in syslog) is very quite during this period -
the only messenges I get are the eth0 promiscuous mode messages that
tcpdump triggers when it runs.

My messenges file just lists the mounts:

(yep, unrelated last line just to show nothing is going on)

100% true, as I noticed as I pressed "y" to send. :-)
