i think the likelihood of this is extremely low -- if your binary is
so borked it can't run at all, methinks none of your binaries will run
(since you have probably messed up the dynamic linker or something).

not really an issue IMO, and comparing two images on size alone
garners no real information.

ultimately, you can always just bypass systemd with `init=/bin/bash`
or, if dynamic libs were fuxxed, `init=/bin/busybox`, or even
`init=/usr/lib/initcpio/busybox` ... which will get you a root shell.

... and if you can't get that far then you need a rescue image anyway,
and systemd coundn't have prevented that.
