Cool, that is definitely a useful improvement for folks who want to
(semi-)automatically provision a large number of rumprun unikernels and
still keep track of what they are doing.
I assume your motivation for the integration with systemd is to start
services as a set of unikernels when a host boots up.
This very problem just came up for our MirageOS unikernels as well. Has
anyone actually got systemd playing nicely with on-demand launching of
kernels with xl? Magnus (CCed) has been refreshing his "Jitsu" daemon 
which launches a Xen VM in response to network traffic, and we observed that
its featureset is rapidly set to collide with systemd/launchd...
That said, I wonder if -i should not be called -i. Enabling the use of
interactive mode non-interactively is, um, weird ;)
That is a little odd. Something like "-n" would be closer to what the ssh
