About Solaris 8 Branded Zones

A Solaris 8 branded zone (solaris8) is a complete runtime environment for Solaris 8 applications on SPARC machines running the Solaris 10 8/07 Operating System or later. The brand supports the execution of 32-bit and 64-bit Solaris 8 applications.

solaris8 branded zones are based on the whole root zone model. Each zone's file system contains a complete copy of the software that comprises the operating system. However, solaris8 zones are different from native whole root zones in that central patching is not applied.

Note that the setfacl and getfacl commands cannot be used with ZFS. When a cpio or a tar archive with ACLs set on the files is unpacked, the archive will receive warnings about not being able to set the ACLs, although the files will be unpacked successfully. These commands can be used with UFS.

Adding Components

You can add the following components to a solaris8 branded zone through the zonecfg command:
