# Role-script for the generalised editing of files for guests.
#
# This script works via a skeleton directory containing small
# .sed files which will contain edits to be applied to an arbitrary
# tree of files upon the new domU.
#
# For example if we have the following sed file:
#
# /etc/xen-tools/sed.d/etc/ssh/sshd_config.sed
#
# this will be applied to /etc/ssh/sshd_config upon the new guest
# *if* it exists. If the file encoded in the name doesn't exist then
# it will be ignored.
