+
When the PXE loader is set to `none`, {Project} does not populate the `next-server` option into the DHCP record.
+
If the `next-server` option remains undefined, {Project} uses reverse DNS search to find a TFTP server address to assign, but you might encounter the following problems:

* DNS timeouts during provisioning
* Querying of incorrect DNS server.
For example, authoritative rather than caching
* Errors about incorrect IP address for the TFTP server.
For example, `PTR record was invalid`

+
If you encounter these problems, check the DNS setup on both {Project} and {SmartProxy}, specifically the PTR record resolution.
If the `next-server` option remains undefined, {Project} calls the {SmartProxy} API to retrieve the server name as specified by the `--foreman-proxy-tftp-servername` argument in a `{foreman-installer}` run.
If the {SmartProxy} API call does not return a server name, {Project} uses the hostname of the {SmartProxy}.

`filename`::
The `filename` option contains the full path to the file that downloads and executes during provisioning.
