Am făcut un script cu care poţi compila automat kernelul linux asemănător cu cel creat de r4zv4n dar totuşi diferit.
Nu mai este nevoie să scoţi manual de pe net arhiva cu kernelul, şi să o decomprimi, lucrurile astea sunt făcute automat.
Ţi se cere versiunea kernelului pe care vrei să o downloadezi şi compilez, şi script-ul o scoate automat de pe kernel.org. Apoi dezarhivează, te lasă să configurezi kernelul, şi în final îl compilează şi creează imaginea.
Updatează GRUB sau LILO, în funcţie de opţiunea aleasă, şi la sfârşit poate restarta sistemul.
Scriptul afiseaza veriunea de kernel pe care o are utilizatorul...
Iată script-ul:
Ver 1.8:
Code: Select all
#! /bin/bash
# Automatic Kernel Build Script
# ver 1.8
#
# Changelog:
# v 0.1 - Original simple code.
# v 0.2 - Added automatic download and unpack code.
# v 0.3 - Added spacing between comands.
# v 0.4 - Added configuration interface options.
# v 0.5 - Fixed some bugs.
# v 0.6 - Added bootloader configuration for grub and lilo.
# v 0.7 - Added restart option at the end of the script.
# v 0.8 - User can now specify the partition where you can find the bootloader.
# v 0.9 - Fixed some bugs. Now the script makes initrd.
# v 1.0 - The script first lets you know what kernel version you run on you system.
# v 1.1 - Added colors to the script.
# v 1.2 - Fixed some bugs and commented the code more carefully.
# v 1.3 - Added a new line and commented the code more carefully.
# v 1.4 - Fixed some bugs and added an option to clean the previous kernel code or not.
# v 1.5 - Added Download possibility and Make Dep for 2.4.x kernels.
# v 1.6 - Fixed some bugs. Now the script is correctly adding the new kernel to grub.
# v 1.7 - Commented out initrd lines.
# v 1.8 - The script now automaticaly detects your bootloader and configures as necessary.
