Michael Meffie 40dfd90a9f externalize log rotation
Do not create new server log files when servers are restarted by
default.  External log rotation tools may be used to rotate the logs by
renaming log files and then signaling server processes to reopen
log files.

Add the -transarc-logs option to each server to provide backward
compatibility with the traditional Transarc-style logging.  When
-transarc-logs is given, log files are renamed to an ".old" file
(overwriting the existing ".old" file) and the previous the log file is
truncated.

=head1 NAME
BackupLog - Traces Backup Server operations
=head1 DESCRIPTION
The F<BackupLog> file records a trace of Backup Server (B<buserver>
process) operations on the local machine and describes any error
conditions it encounters.
If the F<BackupLog> file does not already exist in the F</usr/afs/logs>
directory when the Backup Server starts, the server process creates it and
writes initial start-up messages to it.
The file is in ASCII format. Administrators listed in the
F</usr/afs/etc/UserList> file can use the B<bos getlog> command to display
its contents. Alternatively, log on to the machine and use a text editor
or a file display command such as the UNIX B<cat> command. By default, the
mode bits on the F<BackupLog> file grant the required C<r> (read)
permission to all users.
The Backup Server records operations only as it completes them, and so
cannot recover from failures by reviewing the file. The log contents are
useful for administrative evaluation of process failures and other
problems.
