NAME

     zgenhostid — generate and store a hostid in /etc/hostid

SYNOPSIS

     zgenhostid [hostid]

DESCRIPTION

     If /etc/hostid does not exist, create it and store a hostid in it.  If the user provides
     [hostid] on the command line, store that value.  Otherwise, randomly generate a value to
     store.

     This emulates the genhostid(1) utility and is provided for use on systems which do not
     include the utility.

OPTIONS

     [hostid] Specifies the value to be placed in /etc/hostid.  It must be a number with a value
     between 1 and 2^32-1.  This value must be unique among your systems.  It must be expressed
     in hexadecimal and be exactly 8 digits long.

EXAMPLES

     Generate a random hostid and store it

             # zgenhostid

     Record the libc-generated hostid in /etc/hostid

             # zgenhostid $(hostid)

     Record a custom hostid (0xdeadbeef) in etc/hostid

             # zgenhostid deadbeef
