Oh, strange. Then maybe it's just the userns-patched 3.8 kernel that was sent to this list a while back (it was an Ubuntu ppa, I can't find the posting on the fly) that behaves differently. Then maybe all of this is just a false alarm. (The above commands produce two ro mounts in my test VM.) (Although, I just also tested in on a Fedora 16 box with kernel 3.6.10 and with mount --make-rprivate / before executing your commands and that also produced two ro mounts...) Perhaps Ubuntu has a patch against standard upstream that reverses the behaviour? -- Christian ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
