That's unfortunate. Is there any particular reason it was removed? I think having a 'directory' format, or even a 'mount' one where libguestfs handles mounting/unmounting would be nice.

I'm setting up a system to run LXC containers with ZFS on Linux (Ubuntu 14.04). I intend to set up a base image which I'd like to clone to create other containers from. virt-sysprep and virt-customize seem ideal for the task: I obviously could mount and work with the rootfs from each container directly, but the libguestfs tools have a bunch of pre-existing recipes that would surely be much better than what I'd come up with on my own.
Unfortunately, I can't seem to find any way to tell the tools to work directly on an already mounted directory (from a ZFS subvolume) instead of a disk image.
Am I missing something or is this currently not possible?
This was actually a feature of the original virt-sysprep (1.14). However we removed it in a more recent version (1.16 IIRC). So no, virt-sysprep etc only work on disk images, not on mounted filesystems.
