Release 8.0.0 new features

Initial system installation and upgrades

The menus and options available during an initial system installation of Open UNIX 8 have been updated, and installation on 1 GHz and faster systems is now supported.

Please observe the following limitations when installing Open UNIX 8:

CD-ROM installs

Post-installation addition of non-self-updating packages (e.g. osmp, mpio, or kdb, etc.) from the base directory of the CD-ROM via pkgadd or the scoadmin application installer does not result in a prompt to re-apply the update package before re-booting (and re-linking the kernel). The UpdateSet set must be re-applied from the Updates CD after installing one of these packages, as follows:

   pkgadd -d cdrom_mount UpdateSet

where cdrom_mount is the device where the CD-ROM is mounted (e.g., cdrom1).

Network installation

The network installation floppies have been updated and contain the latest network driver support (see ``Network Interface Card (NIC) Drivers''). Support for network installation via the IPX/SPX protocols has been removed.

networking support

Networking support should be selected during initial installation (if desired), although configuration can be deferred.

/var and /var/tmp

The /var and /var/tmp file systems are mounted by default as memfs file systems that take advantage of the new global_swapmax option. They now share a global memory pool, instead of the previous behavior of having private memory space for each file system. See also ``memfs swap space''.

HBA floppies

The single Host Bus Adapter (HBA) floppy has been replaced by a two floppy set. As with previous releases, when initially inserting multiple HBA floppies that share a driver, the first instance of the driver will take precedence. The HBA floppies are prompted for re-insertion in reverse order (before building the kernel and rebooting) to maintain this precedence. See ``Host Bus Adapter (HBA) Drivers''.

UDI HBA floppies

Please see ``Uniform Driver Interface (UDI)'' for information on using UDI HBA floppies.

updated media images

The operating system datastream on the install media has been recut to incorporate the Release 7.1.1 update, so the Open UNIX 8 fresh install is performed by installing a recut version of UnixWare 7 (711-recut) followed by the UpdateSet set.

Individual 711-recut packages will be provided on the install media, so you can install them later if you do not select them during the initial install. Some of these packages will require that the UpdateSet be reapplied afterward. These 711-recut packages on CD1 should only be installed on Open UNIX 8 Release 8.0.0 and are not supported on previous releases of UnixWare 7.

Installing UnixWare 7 packages

After installing Open UNIX 8, some applications may fail to install because they are expecting to be installed on a UnixWare 7 system. Follow these steps to install packages intended for earlier releases, such as nscomm (Netscape Communicator 4.61), on Open UNIX 8:

If you have a CD-ROM containing the file system image of the nscomm package, insert the CD-ROM containing the package image in the drive, and copy it to a local directory, as in this example:
```
   pkgtrans cdrom1 /var/spool/pkg nscomm
```
The above commands create a directory named nscomm under /var/spool/pkg, with all of the package files under nscomm.
If you have a data stream or single-file format image of the package (e.g., NScomm4.image), use the pkgtrans(1) command to transfer it into a file system format, as in this example of a datastream image, NScomm4.image, in the current directory:
```
   pkgtrans $PWD/NScomm4.image /var/spool/pkg nscomm
```
The above command creates a directory named nscomm under /var/spool/pkg, with all of the package files under nscomm.
Edit the applications pkginfo(4) file (pkgname/pkginfo, or /var/spool/pkg/nscomm/pkginfo using the example from Step 1), and add a line like the following to the end of the file:
```
   SCOMPAT=5:7.1.1:UnixWare
```
Then, save the changed file. See the uname(1) manual page for an explanation of the SCOMPAT variable. Also see ``uname(1) changes''.
Edit the applications pkgmap(4) file (pkgname/pkgmap, or /var/spool/pkg/nscomm/pkgmap using the example from Step 1), and find the line containing the string ``pkginfo''. It will look similar to this:
```
   1 i pkginfo 252 18879 966009354
```
Delete all the numbers after ``pkginfo'' on this line, and save the changed file.
You should now be able to install the package from the edited file system image without any warning about an incorrect release, as in:
```
   pkgadd -d dir pkgname
```
where dir is the directory containing the edited file system image, and pkgname is the name of the package, or using the example from Step 1:
```
   pkgadd -d /var/spool/pkg nscomm
```

Enhanced application compatibility (acp) package

The following commands from the acp package are no longer installed or supported:

   /usr/bin/dosslice
   /usr/sbin/fixshlib

Netscape Communicator 4.61 (nscomm) package

You must follow the instructions found above, under Installing UnixWare 7 packages to install Netscape Communicator 4.61 on Open UNIX 8.

Network Information Service (nis) package

The Network Information Service (nis) package is no longer selected by default and must be manually selected, if desired.

installsrv(1M)

The installsrv(1M) command has been updated to fix problems staging the network install of the software on the Base OS and Updates CD-ROMs (the first and second installation CDs). The command now supports both UnixWare 7 Release 7.1.1 and Open UNIX 8 Release 8.0.0 network installation (using the appropriate media).
