There no default installation, there are six of them.
Six clusters of packages are defined, each one including the packages of the previous one plus new packages. One of them is selected at installation time:
- SUNWCrnet Reduced Networking Support software group
- SUNWCreq Core System Support software group
- SUNWCuser End User Solaris software group
- SUNWCprog Developer Solaris software group
- SUNWCall Entire Solaris software group
- SUNWCXall Entire Solaris software group plus Original Equipment Manufacturers (OEM) support
The SUNWaccu and SUNWless packages are only available when SUNWCall or SUNWCXall software group is selected.
You can see which software group was initially installed on a particular system by looking at the file
/var/sadm/system/admin/CLUSTER.
Of course, nothing prevents the administrator to add or remove packages afterwards.
