Well, what do you expect? I mean, you want to run the tool offline, so
you need to be able to run it on the machine you want to run it offline

systemd is written in C. Sorry.

Note that there's no need to the systemctl version to be in sync of the
image you are putting together and the OS you build it on. The code in
systemctl has been stable since quite a while now. Most distributions
should include it, unless you run Slackware or so. But systemd upstream
is really not the place to work around your weird choice of distro to
build systemd images from...

That said, "systemctl enable" just creates a couple of symlinks in
/etc/systemd/system, you can easily do the equivalent in a handwritten
shell script.
