Thanks for your analysis, it explains what's happening.

I've tried this, and it does make the boot complete successfully.
However, as a consequence, the shorewall service is not running after
boot (because for some reason it fails to properly start the first
time), and will never be running again unless I explicitly "start" it
manually (because the test on the left hand side of && will always be
false).

Arguably, this might be a bug in shorewall's init script (that shouldn't
fail at boot) or, more likely, due to the fact that shorewall lacks a
service description that tells systemd to retry running it later on,
when the network is available.  If you've any idea/tip about this, I'd
appreciate.

In the meantime, feel free to deal as you please with this bug.

Cheers.
