/etc/sysconfig i18n

clock /usr/share/zoneinfo/Asia/Seoul 을 /etc/localtime 로 복사할 것.

Build, or linuxrc or here rm /etc/X11/xorg.cong /etc/sysconfig/hwconf /etc/sysconfig/mouse

kmodule 을 변경하여 사용해야 함. initscripts-7.93.2

• kmodule 의 경우 probeDevice 에서 PROBE_NOLOAD 옵션을 주지만, 현재 이 옵션은 probeclass 가 CLASS_NETWORK 로 설정되어 있는 경우에만 영향을 줌. CLASS_UNSPEC 로 되어 있으므로 현재는 PROBE_ALL 과 같은 결과일 것임.

knoppix-autoconfig 의 부분이 추가되어야 함. 여기에 /etc/sysconfig/pcmcia 에 쓰는 부분을 추가해야 함. kmodule 뒤에 추가하는 것이 맞는지? berry 의 경우 관련 드라이브를 모두 blacklist 에 넣어 놓았슴.

kernel bootloader 를 설치하면 생성됨. installer 에서 고려해야 함.

How is Udev Integrated on Fedora? initrd / initfs

mkinitrd copies /sbin/udev.static to the initrd /sbin/udev and symlinks it to /sbin/udevstart.

After the kernel boots, it executes the nash script of the initrd. This mounts a tmpfs filesystem on /dev/. Instead of hotplug /sbin/udev is called in the initrd phase. udevstart creates all device nodes for the devices, which are compiled in the kernel and for the modules, which are loaded by nash. Problems The whole udev and hotplug infrastructure is not available in initrd. Thus no hotplug scripts, udev rules, and permissions and no /etc/dev.d/ scripts are executed for any hotplug event, which is sent from the kernel. rc.sysinit

First, if SELinux is loaded and enabled, the context of /dev/ is set. rc.sysinit calls /sbin/start_udev. start_udev mounts a tmpfs filesystem on /dev/, if there is none already mounted. Then it creates some device nodes, which need module autoloading, or where there is no kernel module. After that /sbin/udevstart is called again, which simulates the hotplug events in the initrd phase, to apply the whole udev rules and permissions. After that rc.sysinit parses the ouput of /sbin/kmodule and loads every module. This should provide device nodes for all hardware found on your computer. Console User Permissions

/etc/dev.d/default/pam_console.dev is called whenever a device node is created and calls /sbin/pam_console_setowner with the filename (and an optional symlink) of the device node. This sets the permissions for console users like specified in /etc/security/console.perms.
