This section describes processing detail of initial configuration script.

2.12.1 Processing detail of initial configuration script

The following processings are executed by initial configuration script.
1. Change of default setting of SELinux
Change setting of SELinux from "Enforcing" (OS's default setting) to "Disabled" so that SELinux is to be
used only when it is necessary.
2. Change of activation of service
Stop services that required by unsupported hardware or not to be used for server.
– avahi-daemon
– bluetooth
– cups
– NetworkManager
In system environment where the package group of Virtualization Platform is not installed, stop
libvirt-guests service to suppress the unnecessary message issued at shutdown.
3. Exclude update target of yum
To exclude the kernel-related module from update target of yum, add "kernel-*" to exclude line of
"/etc/yum.conf".
4. Installation of 32-bit library
When installing the library package that provides both 32-bit and 64-bit version in x86_64 environment
by using yum, add "multilib_policy=all" to "/etc/yum.conf" to install 32-bit library together with 64-bit
library.
5. Deletion of package of Subscription Manager
Delete subscription-manager, subscription-manager-gui, and subscription-manager-firstboot packages
to suppress unnecessary popup message of subscription manager when desktop environment is used.
6. Interval of information collection
Change interval to collect sysstat information from 10 minutes (default) to 1 minute so that system status
can be obtained more precisely at the occurrence of failure.
7. Creation of backup file
If the file is modified while running initial configuration script, the backup file immediately before applying
the script is created in the following directory.
/opt/nec/setup/backup/rhel6_5_x86_64_nec_setup_<date *1>_<Boot kernel *2>
*1 Date when script is executed
*2 Boot kernel used when script is executed
* Depending on an environment where the initial configuration script is to be applied, it may not
need to modify the file. In such a case, no directory or no file is created under the backup
directory.
