A wad of stuff is an entire solaris distribution made up of all of the different "stuff" eg. admin, install, desktop etc... which are each developed as "consolidations" when collected together they form the "wad" or complete distribution.
All of our Solaris boxes have "wos" except for one:
We have several other Solaris 9 boxes that have "wos" in the release file, this is the only oddball. What's the deal here? I'm guessing that hw is probably hardware and pl is patch level. But where's the wad? Other hardware releases have a wad. Example: Solaris 8 2/04 s28s_hw4wos_05a SPARC
It may or may not be. SHWP versions of Solaris were shipped with Netra machines up until a few years back. I can't remember the full details but I do recall it being the "hardware oem" version of Solaris I believe it means "Solaris hardware program" and that it disappeared as a separate version when it was merged back sometime during the early updates of Solaris 9.
