# XXX: This file isn't *quite* a script. It is intended to be passed via stdin
|
|
# to a node to requisition logic up node creation. Currently this is done in
|
|
# colo_node_requisition using the eval-cat trick. While this gets us what we
|
|
# want, care must be taken to ensure variable expansion happens at the right
|
|
# time. Any unescaped variable references ($X) in this file will be expanded by
|
|
# eval in colo_node_requisition. Escaped variable references (\$X) will be
|
|
# expanded upon execution on the remote node.
