Symptoms:
	PHCO_25065:
	Ported HP-UX patch PHCO_22664 to VVOS

	Based on HP-UX patch PHCO_22664:
	1. Boot records are not getting added if /var is a
	   mounted filesystem.
	2. Console hangs in single-user mode.
	3. init(1m) should execle non-login shell to prevent
	   problems with profiles.
	4. init(1m) writes error message into utmpx file,
	   preventing further logins

	PHCO_18674:
	Ported HP-UX patch PHCO_14105 to VVOS

	Based on HP-UX patch PHCO_14105:
	1. Missing "critical" tag in the Category Tags field of
	   the previous patch PHCO_13213.

	Based on HP-UX patch PHCO_13213:
	1. If shared library is missing or /etc/pam.conf wrong,
	   booting system into single user will cause /sbin/init
	   to go into infinite loop.

Defect Description:
	PHCO_25065:
	Ported HP-UX patch PHCO_22664 to VVOS

	Based on HP-UX patch PHCO_22664:
	1. init is not able to add boot records to /var/adm/wtmp
	   when /var is a mounted file system which will not be
	   available initially during boot time.
	Resolution:
	   Now init(1m) forks a child which checks every 20 seconds
	   that /var is available(mounted) or not. Whenever it is
	   available it writes the boot records in /var/adm/wtmp.
	   Child checks for availability of /var/adm/wtmp upto
	   maximum 50 times.

	2. Console hangs in single-user mode.This is because
	   init(1m) applies bad termios.
	   Problem is due to an unset CREAD termio control flag
	   in the /etc/ioctl.syscon.
	Resolution:
	   Now the code is changed to address this issue.

	3. init(1m) should execle non-login shell to prevent
	   problems with profiles.
	Resolution:
	   Changed the shell structure "-sh" to "sh".

	4. init(1) deamon writes error messages to stderr.
	   The message written to perror goes to one of the
	   open files. For example. The init(1m) may write to
	   utmpx file. This will disallow the rlogin or telnet.
	Resolution:
	   Now the code is changed to address this issue.
	   Now all the error messages will be written to
	   syslogd(1m) log file.

	PHCO_18674:
	Ported HP-UX patch PHCO_14105 to VVOS

	Based on HP-UX patch PHCO_14105:
	1. Missing "critical" tag in the Category Tags field
	   of the previous patch PHCO_13213.

	Based on HP-UX patch PHCO_13213:
	1. Under some conditions, /usr/bin/su fails.
	   This is the first shell tried by /sbin/init when booted
	   into single user mode, and failure of su in some
	   situations results in /sbin/init entering into an
	   infinite loop, rendering the system unusable.
	Resolution:
	   Now the code is changed to address this issue.
