The program systemd is the process with process ID 1. It is responsible for initializing the system in the required way. systemd is started directly by the kernel and resists signal 9, which normally terminates processes. All other programs are either started directly by systemd or by one of its child processes.

The system initialization system used in SLES 15 is systemd. It is a modern and powerful system and service manager that replaces the traditional init system. It provides faster boot times, better dependency handling, parallelization, and more features and capabilities.

If the file1.txt file already exists in your home directory, the touch -7file1.txt command will change the access and modification times of the existing file1.txt file. The touch command can be used to create new empty files or update the timestamps of existing files. The -7 option specifies that only one timestamp should be changed instead of both.

When using the nice command, -15 is the higher priority than 7. The nice command can be used to run a process with a modified scheduling priority. The priority value ranges from -20 (highest priority) to 19 (lowest priority). The default priority is 0. Only root can assign negative priority values to processes.

If you are setting up a SLES 15 server that will require very large data volumes and journaling capabilities, the best choice for your data volumes is XFS. XFS is a high-performance and scalable file system that supports large files and file systems, online defragmentation and resizing, metadata checksums, and other features. XFS also provides journaling capabilities that ensure data consistency and integrity in case of system crashes or power failures. XFS is the default file system for data partitions in SLES 15.

The network interface type supported by SLES that is used for link aggregation is bond. Link aggregation is a technique that combines multiple physical network interfaces into one logical interface for increased bandwidth and redundancy. A bond interface can use different modes and options to balance traffic and handle failures. References:https://documentation.suse.com/sles/15-SP3/html/SLES-all/sec-network-bonding.html

The openSUSE Leap version of Linux is designed for desktop power users and developers. It is a community-driven distribution that offers a stable and reliable operating system with cutting-edge software and tools. It is suitable for personal use, development, testing, and experimentation. It is not intended for high-availability or data center environments that require enterprise-level support and security.

The Linux kernel is started by the BIOS or UEFI firmware during the boot process, depending on the hardware architecture. The BIOS or UEFI firmware is responsible for initializing the hardware and loading the boot loader from a boot device. The boot loader then loads the kernel and passes some parameters to it.

The two commands that are commonly used to compile and install from source code are ./configure and make install. The ./configure command will check the system for dependencies, set variables, and generate a Makefile. The make install command will use the Makefile to compile the source code and copy the binaries and files to the appropriate locations.

To restrict access to your server via SSH to just a few specific users, you need to modify the AllowUsers option in the /etc/ssh/sshd_config file. This option specifies a list of user names or patterns that are allowed to log in via SSH. Any user name that does not match the list will be denied access. You need to restart the sshd service for the changes to take effect. References:https://documentation.suse.com/sles/15-SP3/html/SLES-all/sec-ssh-server.html#sec-ssh-server-config

Log file rotation is the process of compressing or deleting old log files to save disk space and improve performance. The /etc/logrotate.conf file controls the global settings for log file rotation, such as frequency, size limit, compression method, etc. The /etc/logrotate.d/ directory contains configuration files for specific log files that can override the global settings in /etc/logrotate.conf. The /usr/sbin/logrotate program is used to perform log file rotation according to the configuration files. It is usually invoked by a cron job in /etc/cron.daily/logrotate.
