Not really. I invested a significant amount of effort to revert sysv-rc
to sequential booting because the parallel one invites huge amounts of
trouble, bugs, and breaks any hope of debugging that.

Bah. How often do you boot a unix?

And in practice, shitdown times are MUCH more important than boot times.
Need to quickly turn off the laptop because the battery is dying or the
train is arriving or the cat’s vomited all over something. Enter those
90-second delays (often multiple) of shitstemd ☹ sysvinit/sysv-rc shuts
down in good time.

Hey! mksh is there, too! (And /bin/lksh is even linked statically, which
is another performance benefit.)

No, the problem is that they do, by default, even in sysv-rc.
