how do i reduce kernel in boss linux distribution

Hi,

you can recompile the kernel yourself and only include what you need/want at the configure stage.

I'd not heard of "boss linux" before, but a quick search shows that it is derived from Debian. So, you can follow the standard Debian procedure using make-kpkg from the kernel-package package.
See for example:
http://debian-handbook.info/browse/s...mpilation.html
and/or the documentation that comes with kernel-package.

HTH,

Evo2.

The Linux kernel is not terribly 'large' to begin with ... but you can reduce the size of the thing and also improve startup time either by removing unneeded packages or by configuring the kernel to omit unnecessary modules. (For example, an early Red Hat distro had a driver for a DecSystem token-ring network card and actually tested for its presence every time you booted up.) Distros are "designed to start-up on everything, with minimal understanding from their owners," which of course is precisely what many people do want. But they can, if you so choose, be put onto a very considerable diet...

Why ?.

What do you expect to gain ?.

Looking at my Fedora system, and I suspect Ubuntu is similar - the kernel itself is relatively small (4.6M) compared to the standard initramfs file (14.8M). Recreating the initramfs file using only those modules required to boot my system dropped its size by about 69%. I'd go for the low-hanging fruit first.

You can even eliminate the initramfs process altogether, if you put your mind to it. Determine what drivers are actually needed for your actual hardware, then construct a kernel having only those drivers ... built-in for resident devices; loadable modules for USB. "initramfs" is mostly used to fuel the dynamic device-discovery process. The question is how much do your really care.

what are the modules are not necessary in normaly . what does meant initrd?
what is the main fact initrd

what is the in difference systemcall and libraries
