We will be using SysV style init scripts. We have chosen this style because it is widely used and we feel comfortable with it. If you want to try something else, someone has written an LFS-Hint on BSD style init scripts at http://hints.linuxfromscratch.org/hints/bsd-init.txt.
If you decide to use BSD style, or some other style scripts, you can skip chapter 7 when you arive at it and move on to chapter 8.
Install LFS-Bootscripts by running the following command:
cp -a rc.d sysconfig /etc && chown -R root.root /etc/rc.d /etc/sysconfig |
checkfs, cleanfs, functions, halt, loadkeys, localnet, mountfs, network, rc, reboot, sendsignals, setclock, swap, sysklogd and template
The checkfs script checks the file systems just before they are mounted (with the exception of journal and network based file systems)
The cleanfs script removes files that shouldn't be preserved between reboots, such as /var/run/*, /var/lock/*, it re-creates /var/run/utmp and removes the possible present /etc/nologin, /fastboot and /forcefsck files.
The functions script contains shared functions among different scripts such as error checking, status checking, etc.
The halt script halts the system.
The loadkeys script loads the proper keymap table that matches your keyboard layout.
The localnet script sets up the system's hostname and local loopback device.
The mountfs script mounts all file systems that aren't marked noauto or aren't network based.
The network script setup network interfaces (such as network cards) and sets up the default gateway where applicable.
The rc script is the master runlevel control script which is responsible for running all the other scripts one-by-one in a specific sequence.
The reboot scripts reboots the system.
The sendsignals script makes sure every process is terminated before the system reboots or halts.
The setclock scripts resets the kernel clock to localtime in case the hardware clock isn't set to GMT time.
The swap scripts enables and disables swap files and partitions.
The sysklogd script start and stops the system and kernel log daemons.
The template script is a template you can use to create your own bootscripts for your other daemons.
