#
# This class action script is based on the fact that unique identifiers
# used by Sun are reserved for Sun usage ONLY and can be removed or
# updated as needed.
#
# User defined entries and comments in an existing inittab file will be
# preserved and appended to the new ($src) inittab file.
#
# If there is no existing ($dest) inittab file, the script simply copies
# the new ($src) inittab file into place. However, if there is an existing
# ($dest) inittab file, the script attempts to strip out all Sun Reserved
# lines, what remains should be the user defined entries and comments
# which are subsequently appended to the new ($src) inittab file.
#
# The script works by generating two sets of sed parameters which
# will strip out the Sun Reserved unique identifiers from the existing
# inittab file.
#
# PRMVALCUR - a list of sed regular expressions generated from the
# unique identifier field of the new ($src) inittab file.
#
# - this parameter list is generated from the $src inittab file by
# stripping out all comment lines, taking the remaining lines which
# match the regular expression /:(.*):(.*):/ and stripping out the
# two character uniq id field, which is then used to construct a
# a sed parameter list of the type '-e /^<uniq id>:/d' which will
# delete out lines matching the uniq id.
#
# PRMVALOLD - sed regular expression removal parameters for old unique
# identifier entries. These are here in case an existing unique
# identifier is retired in some future version of the inittab file.
#
# - this parameter list is a static list which contains all
# unique identifiers used by Solaris since 2.51 on both sparc and
# x86. If a uniq id is retired from the inittab file it will no
# longer be properly stripped via PRMVALCUR in an upgrade. This
# parameter list insures that uniq id removals in the inittab will
# not require modification of this class action script. This
# script will only require modification if a new entry is made
# to the inittab, which is subsequently removed. In which case
# the uniq id of that entry should be added to this parameter list.
#
# The new ($src) inittab file is copied to a temporary location. The
# existing ($dest) inittab file is then run through sed with the
# parameters defined above. The results are then appended to the
# temporary copy of the ($src) inittab, skipping anything before
# '^#ident', which is where the Sun comment block ends. The results
# are then copied back onto the original temp file to ensure file
# ownership and permissions are preserved. This resulting file
# representing the merge between the old and new inittab is then
# copied into place.
#
# We also pick up any customizations of the ttymon invocation.
