This functionality has been present for more than three years already, but was never properly documented. Fixing that now.

+=== OS configuration file for persistent media ===
+
+If present, the liveslak init will load a OS config file from a persistent Live medium such as a USB stick. In the case of 'Slackware Live Edition' this file is called "/liveslak/slackware_os.cfg" - i.e. is placed in the "liveslak" directory of your USB drive. For custom non-Slackware Live OS-es based on liveslak, the filename may be different.
+This file contains one or more "VARIABLE=value" lines, where VARIABLE is one of the following variables that are used in the live init script:
+ * BLACKLIST, KEYMAP, LIVE_HOSTNAME, LOAD, LOCALE, LUKSVOL, NOLOAD, RUNLEVEL, TWEAKS, TZ, XKB.
+Values for the variables defined in this configuration file override the values already set via liveslak's own defaults or via boot-up command-line parameters.
+
+When booting your persistent //Slackware Live Edition//, the optional boot-time parameter "cfg" deals with this OS configuration file. The "cfg" parameter understands two possible argument values:
+ * "cfg=write" will (over)write the OS configuration file to your USB drive, using the values for all of the above variables that are valid for that particular boot. So if your timezone is "PST" then one of the lines in that file will read "TZ=PST".
+ * "cfg=skip" will skip processing of an existing "/liveslak/slackware_os.cfg" file.
+
+The OS configuration file is not present by default. You either create it at boot-time using "cfg=write" (which is a persistent change) or you create it manually using an ASCII text editor, after mounting theUSB partition on a computer. As an example, here is the content of ''/liveslak/slackware_os.cfg'' on my own USB stick: <code>
+KEYMAP=nl
+LIVE_HOSTNAME=zelazny
+LOCALE=nl_NL.utf8
+TWEAKS=tpb,syn
+TZ=Europe/Amsterdam</code>
