I think you are right. In fact, because "rhgb" is already in $cmdline per default, and "linux norhgb" only adds norhgb
to $cmdline, "rhgb" still matches $cmdline.

Therefore "norhgb" as no effect. As you already mentioned, only "linux nox" and a manual "startx" is working. :-(

To avoid this problem in future releases of the SL LiveCDs, I see three possibilities:

1. remove "rhgb" from the default boot options - no graphical bootup per default.
2. make "norhgb" working - /etc/rc.sysinit has to be modified.
3. (at least) remove "rhgb" from failsafe bootup options.

or just leave it like it is.

Anybody has an opinion on that?


Cheers,

	Urs
