# Build the binary rpms for qmail toaster
#
# This script is invoked by qtp-newmodel.
# It is run in a sandbox (aka chroot jail),
# so the packages aren't installed on the 'live' system.
# This is done so that qmailtoaster can be kept running
# during this (lengthly) processing, and to identify any potential
# problems that need fixing before upgrading a 'live' system.

# change log
# 07/28/10 shubes - changed ARCH to QTARCH to be consistent w/ qtp-newmodel
#                 - pick up variables from qtp-whatami instead of arglist
#                 - added qtp-whatami, qtp-config outputs to log file
#                 - created q51 function to eliminate some redundancy
# 06/28/10 shubes - increated number of lines of log shown to 40
# 08/21/09 shubes - added tail of log to terminal output when build fails
# 08/18/09 shubes - removed stop freshclam - package no longer starts it
# 08/13/09 shubes - fixed bug, allowing packages to be rebuilt
# 07/15/09 shubes - added --replacepkgs for rebuilding installed packages
# 07/23/08 shubes - stop freshclam after installing clamav-toaster
# 01/13/07 shubes - added RPMBUILD_OPT_DIR for package specific options,
#                   replacing hard-coded spambox option
# 01/03/07 shubes - fixed spambox option by adding eval to rpmbuild
#                 - added RPMBUILD_OPTIONS variable
# 12/21/06 shubes - added spambox option for qmailtoaster-admin pkg
# 11/03/06 shubes - added qtp-config to get $SANDBOX, $UPGRADE_DIR
# 10/20/06 shubes - split out qtp-remove-pkgs into separate script
#                 - added qtp-convert
#                 - umount /proc before mounting, just in case
# 08/22/06 shubes - renamed for qt-plus
# 07/15/06 shubes - remove horde-toaster
# 07/14/06 shubes - remove courier-imap-toaster-doc
