ad4c77c29e Remove single-space hard sentence breaks. These degrade the quality 
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

b870a5a3a1 Correct the ttys.5 and init.8 manpages with respect to the incorrect 
assumption that only getty processes can be managed.  Describe the
SysV-like ability to keep arbitrary long-running processes alive
using a non-device first field in /etc/ttys.

81405ca661 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.

b50419cd2e 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.

(b) Mention kernel sysctl variable that controls securelevel.
(c) Add warning the `fsck' will fail if securelevel >= 2.

3fef32ccfc This has always bugged me. At single user, the implied example it gives 
is not valid - it says that "sh" is the default, but you can't
actually type "sh" at this prompt - it has to be /bin/sh or some other
full pathname.

ignore that line in /etc/ttys.  If someone HUP's init, we'll try again.

This change stops getty's from hanging on vty and sio ports that don't
exist, either due to LKM drivers not being loaded, or probes failing.

a9de8ad809 Impose login_cap resource limits on processes started by init. 
/etc/rc started with "daemon" settings.
