I'm asking because the files will=20 be moved from one part of the unionfs (upper) to the other (lower), on=20 different file systems, probably while concurrently accessed. --------------enigF0E61A2C4182F27AC290D583 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iD8DBQFGOw1WldnAQVacBcgRAifyAKDZRfubTl3wGAoJqlBwEMA5LXQf6ACcCdDI P4AUjufsIBVdpRGDNFcVHP4= =v5FX -----END PGP SIGNATURE----- --------------enigF0E61A2C4182F27AC290D583--
