standing ability to list a non-existant device in /etc/ttys to keep it
from dying. This is a documented feature of init(8):
The init utility can also be used to keep arbitrary daemons running,
automatically restarting them if they die. In this case, the first field
in the ttys(5) file must not reference the path to a configured device
node and will be passed to the daemon as the final argument on its com-
mand line. This is similar to the facility offered in the AT&T System V
UNIX /etc/inittab.
So rather than fix the man page to 'break' this feature, back out the change.
At the time this change was made, people felt that the spamage from
getty was annoying on headless consoles. Andrew Gallatin noted:

and we went off and applied this hack rather than fixing getty to
sleep forever when it gets an unknown device, as was Andrew's other
suggestion. Since it breaks things, I'm off to do that instead.
in /etc/ttys. Before this fix, once the count of active services
reaches 0, one could never restart any more without a reboot.
Steve Passe did the leg work on this patch. After he found the fix,
we discovered that an identical fix had been made to NetBSD.

Convert init(8) to use nmount() instead of mount() when
it has to mount devfs. This doesn't happen normally,
since the kernel is supposed to mount devfs itself.
It does not help modern compilers, and some may take some hit from it.
(I also found several functions that listed *every* of its 10 local vars with
"register" -- just how many free registers do people think machines have?)
Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the
entire enclosed block.
not -tag. Instead, put a period after the error messages to aide
those using dumb terminals not capable of properly displaying markup.
