Changes to File System Locations and Names

Some of the changes to file system locations and names are:

• The /dev directory has changed from a flat directory to a hierarchical one.

• The /etc directory contains system configuration information. Several files and subdirectories have been added, removed, or changed.

• The /etc/vfstab tab file replaces /etc/fstab.

• The /etc/lp directory replaces /etc/printcap.

• The SunOS release 5.7 /sbin directory contains the rc scripts used to alter system run levels as well as the rcs script used to initialize the system prior to mounting file systems.

• The SunOS release 5.7 /usr directory contains sharable files and executables provided by the system.

• The /var directory contains files that change sizes during normal operation. Several files and subdirectories in the /var directory have been added, removed, or changed.

• The /var/mail directory replaces /var/spool/mail.

• The /sys directory is no longer needed because the kernel is dynamically loaded.

• The terminfo database replaces termcap.

• The SunOS release 5.7 core kernel is called genunix, and the kernel modules, including 64-bit versions, are stored in the /kernel, /usr/kernel, /platform, and /usr/platform directories.
