Presently, there are a lot of special cases: - runlevel 0 and 6 unconditionally run "script stop" if they find a Kxxscript symlink. This may lead to trying to stop an already stopped device if for example switching to runlevel 0/6 from runlevel 1. This can be fixed by stating the convention that it is the responsability of scripts to check that the service is running before killing it (or not running before starting it). Still, we shouldn't try to stop a service if it was marked K in the previous runlevel. And same for S files: we shouldn't try to start a service that was marked S in the previous runlevel. Note that changing runlevel is not a "reset": if a user has manually changed the state of a daemon, this state will remain the same upon changing runlevel if the S/K status of that dameon is the same in both runlevels. - Sxxscript symlinks in runlevel 0/6 are run as "script stop" instead of the more intuitive "script start". This does not interact well with LSB-tools (some scripts would need "Default-Start: S 0 6" but then it is impossible to get correct "Required-Start" or "Should-Start" fields). Furthermore, having a counter-intuitive behavior is error prone. So now runlevel 0/6 will run "script sart" for a Sxxscript.
Network Configuration:
Script Files:
/etc/rc.d/init.d/*
/sbin/ifup
/sbin/ifdown
/lib/lsb/*
Configuration Files:
/etc/sysconfig/ifconfig.*
Note: ifconfig.* files will be processed
in alphanumerical order on boot, and reversed on shutdown.
- IFACE : The interface that is being configured (e.g. eth0)
- SERVICE: Which script to run in services directory.
- ONBOOT : If set to yes, this interface will be started on bootup
/etc/sysconfig/network
- HOSTNAME: Value of the system's hostname (From LFS Book)
This value may also be set in /etc/sysconfig/rc.site
Additional Configuration:
SERVICE ipv4-static:
- IP : Static IP Address
- GATEWAY : Specifies the IP Address of the gateway server
- PREFIX : CIDR prefix of IP Address, defaults to 24 if not set
- PEER : IP Address of peer (for point-to-point connections and tunnels)
- BROADCAST: Broadcast address
SERVICE ipv4-static-route:
- TYPE : network (default type if not specified), default, host or unreachable
- IP : IP Address of target (for network, host and unreachable)
- PREFIX : CIDR prefix of target (for network, host and unreachable)
- GATEWAY: IP Address of gateway to reach target (for network and default)
SetClock configuration:
Configuration Files:
/etc/sysconfig/clock or /etc/sysconfig/rc.site
- UTC: 1 assumes hwclock is in UTC
0 assumes hwclock is in local time
- CLOCKPARAMS: any additional options to be passed to hwclock
CleanFS configuration:
Script Files:
/etc/rc.d/init.d/cleanfs
Configuration Files:
/etc/sysconfig/rc.site
- SKIPTMPCLEAN: skips cleaning of /tmp directory
/etc/sysconfig/createfiles
