If the hardware clock is set to UTC, this script will convert the hardware clock's time to the local time using the /tools/etc/sysconfig/clock file (which tells the hwclock program which timezone the user is in). There is no way to detect whether or not the hardware clock is set to UTC, so this needs to be configured manually. If you do not know whether or not the hardware clock is set to UTC, you can find out after you have booted the new machine by running the hwclock --localtime --show command, and if necessary editing the /tools/etc/sysconfig/clock file. The worst that will happen if you make a wrong guess here is that the time displayed will be wrong. Change the value of the UTC variable below to a value of (zero) if the hardware clock is not set to UTC time. cat > /tools/etc/sysconfig/clock << "EOF" # Begin /tools/etc/sysconfig/clock UTC=1 # End /tools/etc/sysconfig/clock EOF Contents of Boot-scripts Installed scripts checkfs, cleanfs, functions, halt, localnet, mountfs, mountkernfs, rc, reboot, sendsignals, setclock, swap, and udev. Short Descriptions checkfs Checks the integrity of the file systems before they are mounted (with the exception of journal and network based file systems) checkfs cleanfs Removes files that should not be preserved between reboots, such as those in /var/run/ and /var/lock/; it re-creates /var/run/utmp and removes the possibly present /etc/nologin, /fastboot, and /forcefsck files cleanfs functions Contains common functions, such as error and status checking, that are used by several boot-scripts functions halt Halts the system halt localnet Sets up the system's hostname and local loopback device localnet mountfs Mounts all file systems, except ones that are marked noauto or are network based mountfs mountkernfs Mounts virtual kernel file systems, such as proc mountkernfs rc The master run-level control script; it is responsible for running all the other boot-scripts one-by-one, in a sequence determined by the name of the symbolic links being processed rc reboot Reboots the system reboot sendsignals Makes sure every process is terminated before the system reboots or halts sendsignals setclock Resets the kernel clock to local time in case the hardware clock is not set to UTC time setclock swap Enables and disables swap files and partitions swap udev Starts and stops the Eudev daemon udev
