=head1 NAME
livesys - Reports the configured CPU/operating system type
=head1 SYNOPSIS
=for html
<div class="synopsis">
B<livesys>
=for html
</div>
=head1 DESCRIPTION
The B<livesys> command displays the string stored in kernel memory that
indicates the local machine's CPU/operating system (OS) type,
conventionally called the I<sysname>. The Cache Manager substitutes this
string for the I<@sys> variable which can occur in AFS pathnames; the
I<OpenAFS Quick Start Guides> and I<OpenAFS Administration Guide> explain
how using I<@sys> can simplify cell configuration.
To set a new value in kernel memory, use the B<fs sysname> command, which
can also be used to view the current value. If a sysname list was set
using B<fs sysname>, only the first value in the list will be reported by
B<livesys>.
=head1 CAUTIONS
To see the full sysname list, use B<fs sysname> rather than this command.
B<livesys> is mostly useful for scripts that need to know the primary
sysname for the local system (to create directories that will later be
addressed using I<@sys>, for example).
B<livesys> first appeared in OpenAFS 1.2.2. Scripts that need to support
older versions of AFS should parse the output of B<fs sysname> or use
B<sys>.
=head1 OUTPUT
The machine's system type appears as a text string, by itself, on a single
line.
=head1 EXAMPLES
The following example shows the output produced on a Linux system with a
2.6 kernel:
% livesys
i386_linux26
