Solaris 10 System Administration Part I
My Solaris 10 System Administration Part I notes.
Credits
My main source of information came from Oracle System Administration of Solaris 10 Part I from Oracle University (excellent training) & Solaris 10 man pages.
Solaris 10 OS Directory Hierarchy
File systems
Unix File System (UFS) is the default file system
Directory starts with root directory (/)
Solaris 10 OS includes alternate file system called zettabyte file system (ZFS)
Logically all directories fall below root directory (/)
Physically directories can be located on one or spread over multiple file systems

Refer to filesystem man page for more information on file system organization.
$ man -s 5 filesystem
