Mmm, IIRC, I had to add "acl" and "user_xattr" for my ext3 backup mount point and the ReiserFS which I use for "/" has "notail" as default. But these attributes have to be manually added when you're adding a new disk from scratch, that's what I wanted to note. > What matters are the actual permissions of the root directory of the > filesystem and any other file present on that filesystem.
