I have a patch against base that adds an option "Console" to the Boot
Options sub-menu to prevent a GUI desktop port from being started:
1. Back to Main Menu [Backspace]
2. Load System Defaults
Boot Options:
3. Safe Mode... Off
4. Single User. Off
5. Verbose..... off
6. Console..... off
When set to "On", a kernel environment variable "boot_console" is set to
"YES"; else "boot_console" is unset. A GUI desktop startup script in
${LOCALBASE}/etc/rc.d/ should read this variable and, if set, should
* Ignore a command to start the GUI
* Unset "boot_console" (this allows one to manually start the GUI
after initial boot).
I'm open to suggestions about semantics to make this functionality
clearer (e.g. "Console..... On" is not intuitive).
The problem I have is in the GUI startup scripts, which must be modified
to make this work. What I *want* is to make a *simple* modification to
all GUI startup scripts (e.g. ${LOCALBASE}/etc/rc.d/kdm4) such that
/etc/rc knows what scripts are "GUI startup scripts" and, if
$boot_console is set, performs the above 2 actions. Right now, for me
to make this patch work, I have to add code to my kdm4 startup script to
do this, which would be ugly to add to every GUI startup script in ports.=
Maybe one of the following would be simple/general enough to work:
* Have each GUI startup script declare a variable, e.g. "gui_startup",
which /etc/rc reads to determine whether to disable its startup if
$boot_console is set.
* Have an rc.conf(5) variable "gui_startup_scripts" which holds a list
of startup scripts to not execute if $boot_console is set.
* Have each GUI startup script REQUIRE (i.e. rcorder(8))
"gui_start_check" which fails if $boot_console is set.
GUI desktop port maintainers would have to modify their respective ports
to implement option 1 & 3; the user would have to add her desktop to
/etc/rc.conf for option 2. I'd implement the guts.
Other suggestions welcome.
