I hope Shad would be willing to speak up, for he is fully aware and maintained all 'phone home' and install UUID, EPOCH stuff. Hopefully it will prevent us from re-inventing the wheel.

I agree that a unique ID would be beneficial in the long run and would also eliminate discussions on polluted data -- I was only trying to make a point that we do not need an opt-in for the suggested data.

I have used the MAC address before for that purpose -- before VMs it was unique but now we need to combined with something more. Maybe the UUID for the root device (found via blkid).

f.ex:

/dev/mapper/main-root: UUID="a41a9845-53be-489b-969c-bee4d387af3d" TYPE="ext3"

    needed -- we are not looking for exact science here but marketing
    number and if a few servers are behind the same router/IP that
    will, or should not, disturb the picture much.

    We could and should properly make an opt-in solution if we decided

Although a unique key does not sound as a requirement for you, I know it makes extension to the data model much easier, I think it is not such a big hassle to create one for every server. I could imagine that in the future we would like to now the install base on a per version base and would like to have an update when a machine changes version number for instance, this would be hard to do without a unique id. In other words without the unique ID you do not know if you get duplicates and statistics data is polluted easily, which IMHO defeats the purpose of this exercise.

Kind regards,

Jonathan
