Dear SCO Customer,

Support Level Supplement (SLS) ptf4032c, the SCO UnixWare 2.1 emergency_rec
Update Supplement, addresses all of the problems listed below.


SLS ptf4032a addressed the following issues:

     1. emergency_rec will not save the /usr filesystem if it is
        located on a second hard disk.  A recovery will succeed, but
        the resulting system will not be usable, due to the lack of
        a /usr filesystem.

     2. A block size of 64KB is used when emergency_rec is called
        with the "-d" option.  This block size is not supported by
        some tape drives.

     3. emergency_rec will fail with the message "Duplicate mountpoint
        /dev/swap" when swap and /home2 are on a second hard disk.

     4. Warning messages similar to "/dev/dsk/c0b0t0d0sb busy" are
        produced if /usr and /var filesystems are on separate slices.


SLS ptf4032b addressed the following issues:

     5. An emergency disk creation does not save the disk devices and
        can choose a different root disk on recovery.

     6. /usr/lib/drf/diskop was now included.


SLS ptf4032c additionally addresses these issues:

     7. Following an emergency_rec recovery, the system would panic with a
        "cannot execute /sbin/init" message on reboot.

     8. When using the -d options, the restore and save times are very slow.

     9. On a reboot following a restore, a "cannot find sip" message may be
        displayed.

    10. On some hardware, a "hard disk not sane" message may be displayed
        when booting from the emergency_disk diskettes.


SLS ptf4032c contains the following files:

        /etc/.fboot
        /etc/fboot
        /sbin/emergency_rec
        /usr/lib/drf/bmkdev
        /usr/lib/drf/drf_inst.gen
        /usr/lib/drf/drfram.proto
        /usr/lib/drf/prep_flop
        /usr/lib/drf/tapeconfig


Software Notes and Recommendations
----------------------------------

SLS ptf4032c should only be installed on:

        UnixWare 2.1.0, 2.1.1, 2.1.2 or 2.1.3

SLS ptf4032c supersedes all previous versions of ptf4032; however, it 
is not necessary to remove those SLSs prior to installing SLS ptf4032c.


Installation Instructions
-------------------------

1. Download the ptf4032c.Z file to the /tmp directory on your machine.

2. As root, uncompress the file and add the package to your system

        # pkgadd -d /tmp/ptf4032c
        # rm /tmp/ptf4032c

Alternatively, this SLS package may be installed in quiet mode,
that is, without displaying the release notes and asking for
confirmation.  To do this, use these commands:

        $ su
        Password: <type your root password>
        # uncompress /tmp/ptf4032c.Z
        # pkgadd -qd /tmp/ptf4032c all
        # rm /tmp/ptf4032c

3. There is no need to reboot the system after installing this package.
