Force text mode operation
Force GUI operation (when disabled from the feature dialog)
Force monochrome operation when running in text mode
This one is used when Linuxconf is started from the GUI front-end instead of the reverse. This is generally used in the following case
remadmin --exec ssh some_host linuxconf --guiproto
The big change is that those options are now parsed very early in Linuxconf. This means that the functionality is available everywhere, not just for the main menu. You can now do
dnsconf --text remadmin --exec ssh some_host linuxconf --guiproto --modulemain apache
Note that if you try to configure the system from the boot time menu you must supply the root password. So lynx is allowed after that.
Note also that when you run Linuxconf setuid and a normal user is running Linuxconf and then view a help screen, lynx is run as the real user id, so there is no hole here. This was true in 1.16r0.1 (the first one to support lynx).
The fix only affect the boot time menu help screen.
