rootfs build fails under ciao-down

[grahamwhaley]

Running make rootfs under ciao-down breaks with the following:

Successfully built 2883f6889231
mkdir -p /work/gwhaley/gopath/src/github.com/clearcontainers/osbuilder/workdir

This is with runc as the default runtime (modified ciao-down CC setup), confirmed with docker info.

The command run was sudo -E make rootfs

To run up ciao-down, see: https://github.com/01org/ciao/tree/master/testutil/ciao-down and use the -vmtype clearcontainers option during the prepare phase to get a Clear Container enabled system.

A note - I had my osbuilder git repo in my $GOPATH/src/github.... under ciao-down, which is hosted on a 9pfs filesystem. I wonder if that could be an issue - let me retry this with the repo hosted inside the ciao-down VM filesystem instead...

OK, I can confirm that moving the osbuilder git repo off of the ciao-down 9pfs GOPATH mount and into the $HOME dir fixes the issue. So, this looks like a 9pfs related issue. I'll open an issue over on https://github.com/01org/ciao and link it to this one for xref.
