Re: [rdiff-backup-users] Extended attributes not stored under /mnt/xyz SOLVED

[Simon Blandford]

It seems I needed to add some options in /etc/fstab. Although I'm a bit 
mystified as to why the root partition doesn't also need these options 
specified to work.

So the line in fstab used to read something like
/dev/xxy /mnt/xyz          ext3    defaults 0 0
...and now reads something like....
/dev/xxy /mnt/xyz          ext3    defaults,user_xattr,acl 0 0

BTW. I installed the pylibacl library to get acls to work too.
