if we replace stuff like sysinit by proper C code things become less
fragile and hence you need to debug less.
and secondly, bash is actually a pretty shitty debugger, especially when
there are a lot of scripts running in parallel. For debugging purposes
we should offer better tools, and some of that we already implemneted:
if you pass "systemd.confirm_spawn=1" on the kernel command line you
have the option to single-step through a serialized startup. Tools like
that I believe are much more appropriate for debugging the startup
