Installation guide

8.13 Nemacs
Nemacs Version 3.3.2, a public domain Japanese implementation of emacs,
will be retired in a future release of Tru64 UNIX. Mule, a public domain
multilingual implementation of emacs, will be carried forward as the
replacement functionality for Nemacs. The Nemacs subsets
IOSJPNEMACS440 and IOSJPNEMACSSRC440 will be removed from the
system. For more information on Mule, refer to the mule(1) reference
page.
8.14 Berkeley Software Distribution TTY-NAME
The intent to retire the BSD TTY-NAME namespace was announced in DEC
OSF/1 Version 3.0. This functionality will be retired in a future release.
8.15 SCSI Device Names
Support for rz SCSI device names will be retired in a future release of
Tru64 UNIX. Any code that derives knowledge about a device from the
ASCII name or minor number may be impacted.
All code that uses the current namespace will be compatible when the change
occurs because a mechanism that ensures binary compatibility will be
provided. Existing interfaces such as names and minor numbers will be fully
supported.
8.16 The -x and -p Options in addvol and mkfdmn
The -x and -p options of the addvol and mkfdmn commands allow you
to set the per-volume bitfile metadata table (BMT) when you create a new
volume or file domain. Users typically set the BMT to prevent an extent
exhaustion problem.
In Version 4.0D and later, the limitations in the operating system that caused
the extent exhaustion problem were removed, hence the -x and -p options
are no longer needed and will be retired in a future major release.
8.17 LSM Block Change Logging (BCL)
In the next major release of Tru64 UNIX, the Logical Storage Manager
Block Change Logging (BCL) feature will be retired and replaced by a new
logging method. This new logging method, called Dirty Region Logging
(DRL), will log regions instead of blocks for writes to LSM mirrored
volumes. For most environments, DRL will provide the same ability to
quickly resynchronize mirrors after a failure as BCL, but with considerably
less logging overhead.
