As Matthias said, the "creates" parameter wants a file name, not a
command. I don't see why Puppet would handle it any other way than by
testing for a file with that strange name, which is surely not what you
wanted. Instead, choose a characteristic file and name only it.
But that's not the reason for the behavior you observe. Matthias is also
right that the second command in that '&&' list will not run if the first
exits with nonzero status. ALSO, however, the second will not run if
Puppet uses the 'posix' Exec provider (instead, that provider will pass the
'&&', subsequent command, and command-line parameters as additional
parameters to the first command). If you want to use a shell to run your
Exec 'command' (as apparently you do), then you should specify "provider =>
'shell'" as well.
