## Run the script from /srv (or other HomeDir, if you change the value
## below) like so:
##
## bash sig-atomic-buildscripts/build_ostree_components.sh /srv/builddir
## 
## Other files to edit/check:
##
## atomic-7.1.tdl must point to an install tree avail over http,
## there's a hard-coded IP address there now
## 
## atomic-7.1-cloud.ks and atomic-7.1-vagrant.ks must point to
## the desired ostree repo in line beginning w/ "ostreesetup"
