Most of the system administration directories are
in the root file system. In spite of some
variations, most systems have very similar root
file system directories.
bin - contains public commands
dev - contains special files that define all of the devices
on the system
etc - contains administrative programs and tables
lib - contains public libraries where collections of tested
programs or routines (usually in machine language) are stored
lost+found - used by fsck to save disconnected files
mnt - used to temporarily mount file systems during
a restore of the operating system from backup media
tmp - used for temporary files
u - used to mount the /u file system often found on
many systems
usr - used to mount the /usr file system
/usr/adm - used for various system accounting procedures and files
/usr/spool/uucp and /usr/lib/uucp - used for uucp data and executable files
Other directories of interest that may be present on your system include:
/usr/adm - used for system configuration files
/boot - contains configurable object files created by the /etc/mkboot program
/dgn - contains diagnostic programs
/install - used for installation and removal of software packages
/save - used during backup for saving data on storage devices
bck - used to mount a backup file system for restoring files
And of course several others!
