Unfortunately, this id is either read from /etc/hostid or calculated
from the IPv4 address which a gethostbyhostname_r(3) on the
system's hostname returns.
This means the id is not persistant.
Thanks though,

I've absolutely no idea what you are trying to do here or why. I'm a
little curious about that.
But if you are trying to find a unique id that isn't tied to hardware or
pretty much anything else then why not just make one up.
Here: I wrote this in the middle of this email:
#!/usr/bin/perl
use strict;
use warnings;
use Time::HiRes qw[gettimeofday];
use Digest::MD5 qw[md5_hex];
my $t = [gettimeofday];
my $h = md5_hex($t, rand());
print "$h,\n";
But take out the comma...
It will give you a hex uuid that would be hard to collide with.
If you want, mix the hard drive serial number into the md5_hex array.
