@ -137,6 +137,9 @@ Configure your bootloader to add the following options as necessary:
** The same behavior applies for `aif_password`.
* If `aif_auth` is `digest`, this is the realm we would use (we attempt to "guess" if it isn’t specified); otherwise it is ignored.

== Logging
Currently, only one method of logging is enabled, and is always enabled. On the building host, it can be found on the host and guest at /root/aif.log.<UNIX epoch timestamp>. Note that after the build finishes successfully, it will remove the host's log (as it's just a broken symlink at that point). You will be able to find the full log in the guest after the install, however.

== Debugging
Sometimes it's useful to get a little more information, or to start an installation from within an already-booted environment and you didn't remember (or weren't able to) change the kernel parameters. If this is the case, simply export the `DEBUG` environment variable (it can be set to anything, it doesn't matter) -- if this is done, the arguments will be read from /tmp/cmdline instead. e.g.:

= Writing an XML Configuration File
I've included a sample `aif.xml` file with the project which is fully functional. However, it's not ideal -- namely because it will add my personal SSH pubkeys to your new install, and you probably don't want that. However, it's fairly complete so it should serve as a good example. If you want to see the full set of supported configuration elements, take a look at the most up-to-date https://aif.square-r00t.net/aif.xsd[aif.xsd^]. For explanation's sake, however, we'll go through it here. The directives are referred to in https://www.w3schools.com/xml/xml_xpath.asp[XPath^] syntax within the documentation text for easier context (but not the titles).
