Solaris 包括 UNIX OS, Windows系统(X11), 等.
Solaris1.x = SunOS4.1.x (x>=1) : BSD-like
Solaris2.x 包括 SunOS5.x, OpenWindows3.x, tooltalk, 等.

Solaris2.x is SVR4 (System V Release 4) based. 目的是和目前多数厂家兼容
得更好. IBM,HP,SGI,SCO,...都是SVR-based.

Sun将不再发展SunOS4的产品

Solaris2.5.1支持PowerPC

Solaris2.x  运行SunOS4的程序时采用一种仿真模式. 但是这种支持估计在将来会
被放弃.

Solaris2 的优点:
1) OpenWindows 3.3+ (in Solaris 2.3+).  Includes X11R5 and Display PostScript.
2) Motif & CDE.
3) ANSI-C and POSIX development environment.
4) POSIX threads (2.5)
5) POSIX and X/OPEN command environment
6) Multi-threaded kernel and real threads.
7) True multi-processing.
8) Goodies: vold, admintool and Wabi.
9) Easy patch installation/administration through installpatch.
10) All software in easy to manage "packages".
11) Power management software.
12) Access control lists
13) NFS Version 3 and NFS over TCP (Solaris 2.5+).
14) A better automounter, autofs (not more /tmp_mnt and symlinks).
15) Jumpstart/autoinstall.
16) Better MP support.
17) Faster networking (ATM, fastethernet).
