Personally I am not so sure about having a package create a crontab automatically. It seems like a POLA violation, but it is also something that seems to be expected by some modern applications. I assume it is mostly handled by pkg-message currently, and maybe it is best to continue that way, but having the additional flexibility may be very useful. If for nothing else, it would be a lot prettier than the way I currently manage crontabs using puppet. --=20 Allan Jude --mS8BBbj0is651lEMJ4L6VrsXCNOk0VFE3 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.16 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBAgAGBQJSeTjHAAoJEJrBFpNRJZKfE4AQALdb14F8E5kZh3ay8xMOD0Am Q8H2Av5AsBSM1jzqXDM9xY1fF3W60ePAYIKsGdwdsVW8eatrfFFf/5wNEzz6I0jo +aTMdYLegYSlzaC7xp7uLDRpNZq3dvejbAWSk96nHMQeclQ6yZgyakxe69j0j7KD /gvNNxR8INGa0MmcTKyUI9bkKK1H5jwgJY6S+z00enrdo3orvkYQN4axAqbk/EzV l/tWmgTPdVHyz/S7KmBb+mrdwSqpwlDEM9mhNrWQJfifJhfRvQv1GvLhDv3+QZ5S pgMjF0I7D+GmT2ds5cA+MUuR4gxYPziruOQvFpaVuq+w6qEu/tBoOYhgDXVF+Fyx fbIklfPcuiE9bjMPVdoifpHeeB7ZwvUSCWIiCNXm6T6SGaNtSfy5h2e5YOVmA6// f5cEwVBkwFAct6ivnkysh9iqM4uFUGpbakbGZeyykMMTc1FJU6FnJvLm60ogtQsz 5128AUCU6RucL7AJeIlTVqgDK28qguOf27WP7HWiQjy4ETAIvpiPwYpjUoX79flQ 8/YaZoEzapFhA4DD7kMAaAWBPxtkOH3pSUuewx8qtEGFLYb1k8HbVIgiZp4r+Z1k tfuzCER8UJYJtKq9ch6wjiW44p1dv9wCz9FqVyVoA+D3a/A3AxFhcVDBw+90ajM7 S1QmBd/reYBuaFztYMu3 =MbDX -----END PGP SIGNATURE----- --mS8BBbj0is651lEMJ4L6VrsXCNOk0VFE3--
