Sure. You can do this:
$mustcreate = '/some/file/somewhere'
exec { 'mytask':
command => '/bin/some/command',
creates => ${mustcreate}
}
# In the event the Exec['mytask'] needs to be synced,
# sometime after that sync ensure that the $mustcreate
# file exists:
exec { 'mytask-check':
command => "test -e ${mustcreate}",
subscribe => Exec['mytask'],
refreshonly => true
}
If you want to do that a lot then you can minimize repetition of
boilerplate by creating a defined type around that.
