If set to 'yes', then logging out doesn't kill a user's background processes. Note that this only affects idle-daemon behavior for now. systemd-logind has a similar feature via logind.conf, which this setting does not affect as of now.
If empty or "OFF", the login screen will display as usual. Otherwise, the user "demo" will be logged in automatically, and further behavior is dictated by other variables, such as SLX_AUTOSTART_UUID or SLX_BROWSER_URL.
Contains the location IDs of the currently running client's, from closest to furthest.
As locations are represented as a tree, for example
Main Campus -> Building 101 -> Basement -> Room 4
we have a location ID for each of these "path components". They will be provided as a space separated list in this variable, i.e. the ID of "Room 4" comes first, followed by "Basement", and so on.
If enabled (set to yes), this will add the system-uuid as the DHCP UID (option 0x3d) for all DHCP requests done by the system. This was done by some PXE implementations, so if your DHCP server relies on this identifier to assign consistent IPs to the clients, and you have clients that do this during the PXE step, you might want to enable this.
