Synology and extended attributes

Past time to run Backup Bouncer on my Synology store-everything plan!

One thing to note is that I need --fileflags with rsync to pass the finder-locks test; other than that the two rsync results look the same. Without the errors, those results are:

Verifying: basic-permissions ... FAIL (Critical)

Verifying: timestamps ... FAIL (Critical)

Verifying: symlinks ... ok (Critical)

Verifying: symlink-ownership ... FAIL

Verifying: hardlinks ... FAIL (Important)

The NetworkShare volume is a Synology RS-407 running an embedded Linux mounted via AFP (AppleShare). The permission problems (and ownership and hardlinks and resource forks and ACLs) might be how it's mounted, but I'm concerned about those extended attributes. Might be time to ask Google and friends ...
