Section Number and Name: 
bootloader (required) 
32.5. Package Selection

Describe the issue:
The bootloader --disable and %packages --nocore are not documented in the Installation guide.

Suggestions for improvement: 
The "bootloader --disable" option is a stronger version of the existing "bootloader --location=none", while "bootloader --location=none" disables bootloader installation, "bootloader --disable" disables bootloader installation but also disables installation of the bootloader package (thus saving space).

This also means that if "bootloader --disable" is used using also --location=none is redundant.


Using %packages --nocore disables installation of the core package group which is otherwise always installed by default. Disabling core package group should be only used for creating lightweight containers, trying to install a normal system with --nocore will result in a broken installation.

It should be also noted that:


%packages
-@Core
%end

is not equivalent to

%packages --nocore
%end

Using the - minus syntax for the @Core package group does not work and should not be used. The *only* correct way for excluding the core package group is the --nocore option.


Additional information: 
Strong emphasis should be added to both of these options that they are meant exclusively for container creation and that using them during normal installation *will* result in a broken system.
