# This script will create a baseline list of all the rpm
# files inside a RHEL installation ISO for RHEL 5.X and
# 6.X.

# In order to make the file list directly comparable to
# the output of 'rpm -qa', the file extenstion '.rpm' will
# be removed from all filenames.

# NOTE: On RHEL 5.X 'rpm -qa' does not by default print the
# package architecture. This must be enabled by editing
# /usr/lib/rpm/macros '%_query_all_fmt' value to
# %_query_all_fmt %%{name}-%%{version}-%%{release}.%%{arch}

# USAGE:
# ./create-baseline-pkg-list.sh <path to RHEL iso mnt>
# ex: ./create-baseline-pkg-list.sh /mnt/iso (no trailing backslash)
# ex: ./create-baseline-pkg-list.sh /media
