a69497d73f Finish up umntall support. init now passed an argument to the 
rundown script 'reboot' or 'single'.  ISO support (which never
    worked) has been removed from mount_nfs.  mount_nfs and umount
    now use mounttab, which allows umntall to work properly.  The
    rc scripts now call umntall as appropriate.

a4edcf8989 FreeBSD kernel doesn't allow any process to decrease securelevel. So, 
init(8) cannot decrease securelevel.  The manual page explains this
and single_user() doesn't try to downgrade kernel to insecure mode.

I got a lot of
"getty repeating too quickly on port %s, sleeping"
from init.bsdi, it means that getty start and exit in five seconds.
This is common situation for poor quality Russian phone lines:
modem got CONNECT message and after retries got NO CARRIER.
So I introduce spacing count, it means that this warning and
sleep occurse only after GETTY_NSPACE times of sequental attempts.
----------------------------
revision 1.4
date: 1994/02/28 21:53:52;  author: ache;  state: Exp;  lines: +71 -10
I found (and fix) ugly bugs in init.bsdi (this bugs not present
in old init)

1) Init don't setup TERM environment variable for default terminal
type from /etc/ttys before calling getty/window.

2) When "kill -1 1" issued, init don't restart getty when
/etc/ttys parameters was changed (it only kill "off" end empty entries).

3) Small memory leak if "window" /etc/ttys parameter specified and
"kill -1 1" issued.
