To be completely correct, Solaris is an operating
environment. The
kernel is still
SunOS even though it is regularly
referred to as Solaris. Take the following output from a Solaris 7 system running
SunOS kernel version 5.7:
# uname -a
SunOS myhostname 5.7 Generic_106541-12 sun4u sparc SUNW,Ultra-Enterprise-10000
Solaris encompasses the kernel, the suite of tools provided to a user and the login environment such as CDE.
