sys_id(4)

NAME
     sys_id - system identification (hostname) file

DESCRIPTION
     The file /etc/sys_id contains the name by which the system is known on
     communications networks such as the Internet and UUCP.  The name can be
     up to 64 alphanumeric characters long and can include periods and
     hyphens.  Periods are not part of the name but serve to separate
     components of a domain-style name.  For example:

          iris.widgets.com

     During system startup this file is read by the script
     /etc/rc2.d/S20sysetup and the contents are passed as a parameter to
     hostname(1) to initialize the system name.  Once this has been done, this
     name is returned by the commands hostname(1) and uname(1) and by the
     system calls gethostname(2) and uname(2).  uname(1) returns only the
     first eight characters up to the first period.
