# install-ops.sh - Script to do the initial install of an ops node
#
# The main things it does not do yet:
# * Figure out where to put directories such as /users /proj - they must
#   already exist
# * Fill out mailing list files - presumably, it's easier to just get the
16
#   User to edit them himself
