What type of files are stored in /etc (/bin, /var, /sbin, /boot, /lib)?

  • /etc — system-wide configuration files
  • /bin — essential binaries needed for single-user mode (e.g. ls, cat, cp)
  • /sbin — essential system binaries (e.g. init, ip, mount)
  • /boot — bootloader files (e.g. kernel, initrd)
  • /lib — libraries essential for the binaries in /bin and /sbin
  • /var — variable data (logs, spools)
