Hi Clark,

If you're bind mounting a file, you have to bind it to an existing file, not a directory. Try touching /dev/myloop first, and then mounting the real loop device to it.

Thanks,

Hello,

While trying to get livecd-creator working in a mock-built chroot, I discovered that only directories could be bind-mounted using the bind_mount plugin. I made a few code changes and attached a patch for your consideration that enables the bind-mounting of files. Like directories, the bind-mounting of files will require 'internal_dev_setup' be set to False, otherwise the mount command will fail.

In the chroot configuration file the following syntax would be allowed (which looks just like that which was used for bind-mounting directories):

config_opts['plugin_conf']['bind_mount_opts']['files'].append(('/dev/loop0', '/dev/loop0'))

Please let me know what you think, and thanks in advance for your time!

Jay,

Finally got some time to pull in mock patches and work on bugs. Sorry
it's taken this long...

I'm not seeing how your stuff would work. A bind-mount only works on
directories, not files. If I try to bind-mount /dev/loop0 somewhere by
hand I get the following:

$ mkdir -p /tmp/foo && cd /tmp/foo
$ sudo mount -n --bind /dev/loop0 .
mount: Not a directory
$ mkdir dev
$ sudo mount -n --bind /dev/loop0 dev
mount: Not a directory

What am I missing here?
