Comments and suggestions concerning this book should be mailed to gmourani@videotron.ca © Copyright 1999-2000 Gerhard Mourani and Open Network Architecture ® 89 Step 2 Once the name of the new kernel version has been putted in the “lilo.conf” file as show above, we update our “lilo.conf” file for the change to take effect with the following command: [root@deep /]# /sbin/lilo -v LILO version 21, [Copyright 1992-1998 Werner Almesberger Reading boot sector from /dev/sda Merging with /boot/boot.b Boot image: /boot/vmlinuz-2.2.14 Added linux * /boot/boot.0800 exits – no backup copy made. Writing boot sector. IMPORTANT NOTE: If you say NO to the configuration option “Unix98 PTY support (CONFIG_UNIX98_PTYS)” during your kernel configuration, you must edit the “/etc/fstab” file and remove the line that read: none  /dev/pts devpts gid=5,mode=620 0 0 Delete program, file and lines related to modules By default when you install Red Hat Linux for the first time (like we do), the kernel is built as a modularized kernel. This means that each devices or functions we need exists as modules and are controlled by Kernel Daemon program named kmod, which automatically loads some modules and functions support into memory as it is needed, and uploads it when it’s no longer being used. The kmod as well as other module management programs included in the “modutils” RPM package use the conf.modules file located in the “/etc” directory to know for example which Ethernet card you have, if your Ethernet card requires special configuration and so on. Since we are not using any modules in our new compiled kernel, we can remove the “conf.modules” file and uninstall completely the “modutils” package program. · To remove the “conf.modules” file, use the command: [root@deep /]# rm -f /etc/conf.modules · To uninstall the modutils package, use the following command: [root@deep /]# rpm -e --nodeps modutils One last thing to do is to edit the file  “rc.sysinit” and comment out all the lines related to “depmod -a” by inserting a “#” at the beginning of the lines. This is needed since at boot time the system read the rc.sysinit script to find module dependencies in the kernel by default. Comment out the line 260 in the rc.sysinit file (vi +260 /etc/rc.d/rc.sysinit): if [ -x /sbin/depmod -a -n "$USEMODULES" ]; then To read: #if [ -x /sbin/depmod -a -n "$USEMODULES" ]; then Comment out the lines 272 to 277 in the rc.sysinit file (vi +272 /etc/rc.d/rc.sysinit):     if [ -L /lib/modules/default ]; then         INITLOG_ARGS= action "Finding module dependencies" depmod -a default
