Scott Moser has proposed merging
~smoser/cloud-init:bug/1764264-schema-runcmd-is-not-unique into
cloud-init:master.
Commit message:
Schema: do not warn on duplicate items in commands.
runcmd, bootcmd, snap/commands, ubuntu-advantage/commands would
log warning (and fail if strict) on duplicate values in the commands.
But those should be allowed. Example, it is perfectly valid to do:
runcmd: ['sleep 1', 'sleep 1']
LP: #1764264
