# passwd2alias is meant to be invoked nightly by cron for the purpose of
# adding aliases to the local machine for everyone listed in the passwd
# file.  This shell will usually be used in conjunction with the m4 defines
# HIDDENNET, HIDDENNETHOST in ../ida/cf/machine.m4 on machines using YP.
# Depending in settings in /etc/netgroup, not all users listed in the YP
# passwd file may be local.  This is overcome by listing everybody in the
# alias file ala
#
# someuser:	someuser@serverhost.domain
#
# where serverhost is the machine which all users are local to.
#
# Configuration:
# Alias file:
AliasFile=/etc/aliases
readonly AliasFile
#
# Processing steps:
#
# 1) Copy /etc/passwd to temp file
# 2) Strip everything from the first ':' on each line on.
# 3) Change lines from
# user
#  to
# user:	user@hostname
#

#
# 4) Make a backup copy of AliasFile
# 5) Delete all text from the line with "WILL GO AWAY" to the bottom
# 6) Append warning line from step 5 followed by contents of a2p.$$
