Hello everyone,

I've been using aufs in a netboot environment for a while now and I
noticed that the somtimes timestamps on files aren't updated.

When appending to a file that exists on a lower layer but doesn't
exist on a writable layer yet, the file will be copied up but the
timestamps won't be updated even after closing the file. Once the
file exists on a writable layer, the timestamps are updated on
write as expected.

I'm using the aufs (version 20080922) and kernel (2.6.27-11) from
the Ubuntu Intrepid (8.10) repository.

Could someome try to reproduce this behaviour? Maybe it's already
fixed in the newest aufs version, even though the changelog
doesn't list any related changes.

How to reproduce: Look for a file that can safely be appended but
doesn't exist on a writable layer yet.
echo something >> file
Timestamps should be the same as before.

If you have /var/log on an aufs-mount, check the timestamps of
the syslog files. They should be outdated.
