Hi guys, I've been struggling with similar issue in centos 6.6. In previous version (6.5) everything worked fine, but after update I wasn't able to set socket for ssh control master on overlayfs. I made some tedious research and comparisons and it turned out that it's not about the kernel (made few downgrades) but ssh. According to https://bugzilla.redhat.com/show_bug.cgi?id=953088 in ssh version included in RHEL 6.6 (and CentOS) there was a patch witch modifies behaviour of creating control socket. When I downgraded ssh packages (openssh{,-clients,-server}) to the version without that patch (5.3p1-94.el6) everything worked like a charm!
I hope it will also help you to solve your problem in Ubuntu. ** Bug watch added: Red Hat Bugzilla #953088 https://bugzilla.redhat.com/show_bug.cgi?id=953088 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1214500 Title: consistent failure with overlayfs and unix sockets Status in “linux” package in Ubuntu: Confirmed Bug description: Seems like overlayfs and unix sockets are not playing well.
