#   COMPONENT_NAME: UTILITIES
#
#   FUNCTIONS: none
#
#  Name:  clchipat
#
#  This routine configures/unconfigures IP Address Takeover
#  processing in /etc/inittab and /etc/rc.net
#  
#  If the argument is "true" IPAT is configured
#  If the argument is "false" IPAT configuration is removed
#
#  If /usr/es/sbin/cluster/.use_telinit exists, the legacy telinit a mode is enabled.

#  The old copies of the files are saved as /etc/inittab.orig,
#  /etc/rc.net.orig, and /etc/rc.nfs.orig
#
#  If IPAT is being configured, rc.net is modified to exit if not
#  passed the "-boot" argument from the rc.cluster. Furthermore
#  inittab entries pertaining to network startup are moved to run-level
#  "a" so that they won't be run until explicitly triggered from the
#  cluster software.
#
#  Usage:        cl_chipat "true|false" [-V] 
#
#  Arguments:
#                true - add entries to /etc/inittab /etc/rc.net
#                false - remove entries from /etc/inittab
#
#                -V verbose, show all added, deleted or modified entries
#
#  Returns:      0 - success (no changes required)
#                1 - any system error
#                2 - bad number (0) of arguments
