[gentoo-user] /etc/machine-id ???

[meino.cramer]

Hi,

I found a file /etc/machine-id on my linux box.
I did a qfile for this and nothing was found.

What purpose is that file and can I delete it without problems?

Best regards,
mcc

dbus is creating this file during installation.

  root:506 etc> ls -l machine-id 
  -rw-r--r-- 1 root root 33 Oct 24  2007 machine-id

I don't have that file on any of my machines, however, a quick google reveals 
this may be related to dbus:

http://lists.freedesktop.org/archives/dbus/2011-March/014188.html

Maybe someone else can shed some more light on this?

I dont like the idea of haveing something on my box, which make it
identificable or unique ... thinking of the diskussion of the use
and misuse of a CPU-ID.
Reading /dev/urandom instead is more what it should be in my opinion, 
since that changes from boot to boot...

Paranoia is your best friend.... ;-/

"rm /etc/machine-id" right after the root-partition is remounted RW should 
solve that? :)

I don't know about removing /etc/machine-id, but if you are running
Gnome be careful about /var/lib/dbus/machine-id as not having that one
may cause Evolution to fail to open correctly.
