PROBLEM: (DE_G02408, 90319) (PATCH ID: OSF510-480)
********
This patch fixes a kernel build failure seen during an Update
Installation from CD-ROM.  The problem affects systems whose default
time zone (/etc/zoneinfo/localtime) is not in North or South America.
For example, this problem affects a system in Germany running V5.1
with the symbolic link /etc/zoneinfo/localtime pointing to
./Europe/Berlin.

After the installupdate command loads the new subsets and the system
reboots from the new generic kernel, the custom kernel build fails
with this message:

Make: Don't know how to make kern/lockinfo.c

PROBLEM: (81764) (PATCH ID: OSF510-046)
********
This patch ensures that re-installing a software subset will not erase
existing subset info, even if the re-install fails.

You attempt to re-install a subset that is already on your system,
but the operation fails.  Afterward, you notice any of these
situations:

1.  setld -d (or setld -i) reports the subset is not installed.

2.  You try to load another subset, which has a dependency on the
first, and the load fails due to its dependency check.


PROBLEM: (117-2-285, 83816, 84633, 84517) (PATCH ID: OSF510-198)
********
The installation process rejects a subset name
with an underscore character on a V5.1 system.
The specific system was trying to install the IBM
MQSeries Documentation Base subset, MQS_HTML_PUBS.  The
failure occurs during verification and gives the error,
setld: There were verification errors for "IBM MQSeries Documentation Base"
The deletion process fails when the root account of a member node
is running a shell (such as /usr/bin/csh) that does not support setting
command line environment variables.  When setld uses rsh to execute the
subset control program on the remote cluster member, it fails and gives
the error,
ACT=C: Command not found

The deletion process on a V5.1 system does not terminate
when the C DELETE phase of the subset control program fails.  The user has
no indication that the phase failed. The deletion process continues and
deletes the subset.  The user thinks the process terminated without any errors.
