The installation of a Sun workstation uses an install server, as we mentioned above. The install server acts as a Sun server for a Diskless station.
The server needs a MINIROOT and the information telling it which named station boots which MINIROOT. To avoid enumerating all station which are allowed to boot the MINIROOT (1.2.5) we use wildcarding in the bootparams file. This makes for easy maintenance of the bootparams file but requires the install server to be isolated on a subnet, away from other diskless Sun (real diskless Suns which would be confused otherwise) (1.2.6) and precludes using the same server for two distinct CPU type of Suns.
Up until recently, to install a server we would follow the README file in the bootkit locker, which details how to update the bootparam file and how to untar the MINIROOT. We now have a simpler procedure, a mkserv script (1.2.2, 1.2.3). Once the install server is installed, no maintenance is required, unless some catastrophe happens, in which case we reinstall it.
