Re: [Libguestfs] [PATCH 09/10] New API: mksquashfs

Introduce a new API to create a new squashfs filesystem out of a path in the guest. It can be configured to exclude paths based on patterns, and to select which compression use for the filesystem. The advantage of running mksquashfs directly in the appliance is that ownerships are properly saved, as opposed to tar_out + local untar.
