Shachar Shemesh: At the moment, I can't seem to get things to work, because the capabilities, despite being set on the original file, are not seen by the kernel on through aufs. Is this something I'm missing? Won't you describe more specificaly? What do you call "the capabilities", capget(2)/capset(2), ACL or XATTR? In other words, what did you do (as your set-up and operation) and what do you expect as its result? Hello, and thank you for getting back to me so quickly. I am using the getcap(8) command line utility. According to strace, it is calling capget(2) on the file, resulting is EOPNOTSUPP. The mount is done using the following fstab: none . aufs br=/srv/os1=rw:/srv/baseos=ro 0 0 /srv is a single file system the file being queried resides on /srv/baseos. There is no such file on /srv/os1. Getcap on /srv/baseos directly works and gives the correct result. The system is Ubuntu server 12.04 with kernel 3.2.0-29-generic. Aufs is the one that was compiled into that kernel. I hope this provides all the information you need.
