It's nice to know that there is a fix somewhere.  However, I got a
brand new ADSM V2.1 CD-ROM from IBM Denmark about 10 days ago that
created the very serious problem described above.  Mind you, I will
never have any option of applying the mentioned fixes to my ADSM
installation CD-ROM (read-only medium, you know :-)  You are suggesting
to fix the installation *after* it has corrupted my AIX system, right ?

This problem is one of the most serious software bugs that I have
seen in many years, so I urge IBM to heed the following advice:

RECOMMENDATIONS TO IBM:

1. Withdraw the ADSM V2.1.0.0 CD-ROM from all distribution channels.

2. Send a letter to recent customers warning about potential corruption
   of AIX 4.1 when using the ADSM V2.1.0.0 CD-ROM.

3. Send a fixed CD-ROM to all ADSM V2.1 customers.
