Which means I don't need any other module.
How do i build kernel and world removing "any other module" then listed above ?
 
Why are you loading snd_driver?

Code: 
     MODULES_OVERRIDE
                   (str) Set to a list of modules to build instead of all of
                   them.
....
     NO_MODULES    (bool) Set to not build modules with the kernel.
...
     WITHOUT_MODULES
                   (str) Set to a list of modules to exclude from the build.
                   This provides a somewhat easier way to exclude modules you
                   are certain you will never need than specifying
                   MODULES_OVERRIDE.  This is applied after MODULES_OVERRIDE.
make.conf(5)
 
snd_hda seems to be part of the kernel so i removed snd_driver from rc.conf.
Currently i have

So I did not needed to load the other snd drivers.
 
I'm adding to my kernel config file,

Which means I don't need any other module.
How do i build kernel and world removing "any other module" then listed above ?
Click to expand...

simply look into
Code: 
/boot/kernel
directory for .ko files , for example, any file (correct me if I am wrong) begining with "if_" are network cards, and so long, be very carefull with that

and like SirDice points , put the modules names in /etc/make.conf
example
Code: 
WITHOUT_MODULES if_nge , if_muge

or better, I never try it but you can use
Code: 
MODULES_OVERRIDE
and put the modules that you see in kldstat there

and what if you output of ifconfig?
nevermind,you should have define your network card in your kernel config file for sure
 
maybe is a shoot in the foot, but you can put this in your /etc/make.conf and build your kernel
make sure to have the boot loader menu enabled (to select other kernel if this wont work)
and make a copy of your /boot/kernel directory

You don't need all those nodevice lines. What nodevice does is when you start with an include GENERIC is to remove anything that was included in GENERIC. Most of these aren't included in GENERIC to begin with, so you don't need to nodevice them.

Everything is always built as a module, regardless if you put them in your kernel config or not. The kernel config just defines what's statically included in your kernel. Nothing more. It doesn't tell the system which modules to build and which don't. That's what MODULES_OVERRIDE and WITHOUT_MODULES does.

It's fine to load these as modules. What you do need to include in your custom kernel configuration is everything that's required to actually boot the system. Once the kernel is running and the system is booting the rest can be loaded dynamically as modules. That includes any interface drivers you might need (unless you are network booting the system of course).
 
So i put in make.conf (not src.conf) the line ?

Will this have effect on buildkernel or buildworld or both ?
 
So if i understand correctly to have /boot/kernel less populated you put no_device in KERNCONF.
To have /boot/modules less populated you put the line WITHOUT_MODULES in make.conf
 
Alain De Vos what's the end-goal here? Unless you are space constraint (building for some small embedded device for example) there's really not much to gain. Just save yourself a lot of headaches and let the system build everything. If you're looking to shave off some build time you should look into WITH_META_MODE instead.
 
The end goal is rather very simple. Have a streamlined system where directory /boot contains as little as possible but i can use all functionality i need.
Disk usage "du -h /boot" should be as low as possible.
[If i wanted bloatware i used akonadi/nepomuk/strigi/baloo/UBUNTU.]

Does this line looks sane or not for a desktop PC ?
 
It does not. No excluding of any modules is sane on anything but a space-cramped embedded device.

If you need to save space on a desktop, install from release binaries:
Code: 
$ du -hs /boot/kernel /usr/src
 96M    /boot/kernel
2,7G    /usr/src

To put that further into perspective, the minimum size for a fully compliant ESP, even if containing nothing but a tiny bootloader, is 256M.
 
I think everything worth saying in this thread has been said. So in this rather rare occasion I'll do us the honors of starting the OT:

In fact, it depends on the sector size. There is no specified minimum size, but the filesystem must be FAT32 (not FAT12/16, and a few stupid implementations indeed only accept FAT32). With 4k sectors, this results in an effective minimum size of 256M. With (ancient) 512B sectors, 32M would already be enough.

I don't know if comparison is wise but my /boot directory in gentoo-linux is 3X smaller compared to freebsd.

I don't think it is:
  1. Linux installs kernel modules outside /boot (in /lib/modules).
  2. Look at the absolute numbers, compare to something that really needs some considerable amount of space.
