Hi Josh, Josh Triplett <[email protected]> writes: > On the other hand, I'm somewhat curious what upstream actually *uses* > the machine-id for, and why a machine needs a unique identifier. The only use of the machine-id in Debian that I could find is within the journal:
http://sources.debian.net/src/systemd/44-12/src/journal/journal-file.c?hl=130#L130 Given that the file replaces the old DBus machine-id, if you consider that, we have a few more calls in the archive: http://sources.debian.net/src/consolekit/0.4.5-3.1/src/ck-manager.c?hl=306#L306 http://sources.debian.net/src/kaa-base/0.6.0+svn4596-1/src/utils.py?hl=291#L291 Also, http://www.freedesktop.org/software/systemd/man/machine-id.html explains: Programs may use this ID to identify the host with a globally unique ID in the network, which does not change even if the local network configuration changes. Due to this and its greater length, it is a more useful replacement for the gethostid(3) call that POSIX specifies. While this is not a totally satisfactory answer, I hope it clarifies the intention of this ID. -- Best regards, Michael -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
