Project 1 of 3 in the Linux System Management series
Focus: Boot Process, GRUB2, Timezone Configuration, Kernel Parameters


πŸ“Œ Objectives

  • Inspect and validate the system boot process
  • Review GRUB2 configuration structure
  • Set and verify system timezone
  • List and filter kernel and network parameters using sysctl

πŸ–₯️ Environment

  • Fedora Linux (remote system)
  • SSH access from macOS terminal
  • All commands executed remotely and documented with outputs and screenshots
