So the fix for mount is correct.  I pushed that.

Does Devuan use Debian's packages unmodified or does it recompile
them?  While I understand Devuan's goal is to remove systemd, using
the unmodified Debian libguestfs package won't work because it needs
libsystemd.  It needs it to read journal log files from guests that
use journald, eg. for tools like virt-log accessing, say, a Fedora VM.

You can remove this dependency but only by recompiling libguestfs.
