FWIW if you would chose the "upstart" entry, the output of "uname" would
be the same as the one you posted, since you wouldn't boot another
kernel, just PID 1 would not be systemd. It is not a different kernel.
The boot parameter only changes the init system, which get's the first
process ID. PID 1 is the first "process" ("program") started by the
kernel. This first "program" controls all programs that run during
startup. It means that the first "program", which is started by the
kernel is different, depending on the boot entry you chose, while the
kernel is the same.
