I'm encrypting ~/Private only. There are tons of cronjobs running on
this machine, several of them as my user. The unmount takes place every
now and then, but not with every run of a job. Maybe I have to run more
than one job at once for this to happen? But then again, I think Cron
serializes jobs in order to not start everything at once.

Looking at the similarities of the times of unmounting in the syslog, I
can spot these cronjobs to be running every time it happens:

rss2email as my user - should be harmless
fetch-exchange.py as my user - fetches mail from an exchange server and feeds it to procmail
/usr/sbin/update-motd as root

To my knowledge, none of these jobs should be accessing ~/Private in any
way. Plus most times they are running my ~/Private stays mounted.

I'm still trying to gain some enlighenment by studying the logs. In
addition I will now adjust the start times of my jobs in the hope of
separating the jobs by time.

Bug description:
Binary package hint: ecryptfs-utils

This seems to be bug #259293, but I am filing a new one as I haven't seen this in some time. Twice in the last week my ~/Private directory unmounted. Both times /tmp/ecryptfs-<user>-Private was '0'. Both times, the symlink in the unmounted ~/Private was not present.  I have a cron job that runs every 10 minutes that I can see in syslog:

Apr  9 11:15:04 hostname CRON[22771]: Mount of private directory return code [0]

It could be that bug #259293 is simply 'mostly' fixed and I coincidentally hit this twice in the last week, or it could be a new bug (I don't know).
