.cloud_init_user_data(computer) ⇒ Object

FIXME: users_groups only in 7.4, not 6.3 … including

this module breaks on our Ubuntu image (with cloud-init 6.3)

note that in the sed statement in the bootcmd below,

sed expects some characters to be escaped \(\) etc.
then yaml needs \ inside double-quotes escaped as \x5c
