The developers of the Manjaro Linux distribution, built on the basis of Arch Linux and aimed at beginners, announced the beginning of testing a new service MDD (Manjaro Data Donor), designed to collect statistics about the system and send it to the external server of the project. The author of the MDD intended to enable telemetry by default (opt-out), but the decision has not yet been approved and, judging by the objections of some developers and users, it is likely that telemetry will be offered as an option requiring prior consent of the user (a request to enable telemetry is proposed to be added to the greeting interface after the first download).
The report includes data such as host name, kernel version, desktop component versions, detailed information about hardware and drivers involved, screen size and resolution information, network device MAC addresses, disk serial numbers, disk partition data, information about the number of running processes and installed packages, versions of basic packages such as systemd, gcc, bash and PipeWire.
The sent data is stored on the project server in the ClickHouse database and visualized using the Grafana platform. The IP addresses of users are not stored, and the hash from the /etc/machine-id file is used as the system identifier.
Аccording to the code https://github.com/manjaro/mdd/blob/master/mdd.py#L40 sends everything.
I get the usefulness of technical telemetry such as kernel version, RAM, disk space, processor type, etc… but NIC MAC? HDD serial? WTF?
Yeah that makes no sense lol. Who needs MAC addresses to debug and fix bugs? No one.
Why on earth do they need to know hostname? MAC addresses?
Opt-out? I see it’s time for the seasonal Manjaro fuck up.
hostname? MAC address? serial numbers? does "partitionx data also include names and GUIDs?
why would they need these? what is wrong with them??

That’s insane
enable telemetry by default … MAC addresses, disk serial numbers
Another reason to not use Manjaro. Just use Endeavour instead.
Edit: I’m not against telemetry pre se. I have the KDE feedback enabled for example but that was opt in and sends no unique data.
network device MAC addresses, disk serial numbers
That’s enough. I’m calling it evil from now on.
Thought it’s probably fine after reading the title, but this shit isn’t fine. What the fuck.
The MAC address is anonymized with sha256, and IP adresses aren’t stored.
So this seems to me to be perfectly anonymous.MAC addresses are 48 bit, and half of that is just the manufacturer. So 24 bits really, and those bits aren’t random, I think manufacturers just assign these based on some scheme, like a serial number. Point is you could easily reverse the SHA by brute force.
You can’t calculate any useful statistic from a hash so literally the only use this would have is some sort of tracking.
Edit: I just looked up some data and I found someone using hashcat on an RTX 3090, which looks like it can do almost 10000 million SHA256 hashes per second of salted passwords (which are longer than 48 bit MACs, so MACs should be faster). 2²⁴ is 16.8 million, so it’ll take about 1.7 ms per vendor. I found a database with (all?) 53011 vendor ids:
>>> 2**24 * 53011 / 10000 / 1000 / 1000 88.93769973759998Yup, 89 seconds. You can calculate the SHA256 of every single MAC ever potentially issued in 89 seconds on a bog-standard 3090.
this would have is some sort of tracking.
It’s right at the top of the announcement, that it’s mainly for more accurate stats on unique users.
It’s not that I think this is a good idea, because I don’t, but some people are blowing it out of proportions. Especially since this isn’t at all decided. Which I seriously doubt it will.You don’t need this to count unique users. You could just assign a random number on install or whatever. Or even more simply, just run the thing once per month, should be accurate enough. Do they expect the software to just randomly spam duplicate reports? Don’t write it that way.
Best case they don’t care about collecting minimal data and don’t understand that hashed MACs are easily reversible. So incompetent fools with no sensitivity to privacy.
Maybe this should be Manjaro’s tagline: Not purposely malicious, just grossly negligent and ignorant.
You could just assign a random number on install or whatever.
Funny, I thought the exact same thing.
That list about which data they’re collecting is longer than my highschool essay
data such as host name,
Okay why do they need to know that? Why do they need to know if the computer is called “Melissa’s Laptop” or “Workstation 15, Internal security division”? Seems like this kind of data could if stolen be misused and it has minimal legitimate purpose IMO as anyone can put anything as host name and while in organizations it often corresponds to use it doesn’t have to for individuals. Someone could call their machine “Mack’s Porn Rig” and they only use it for doing banking and a little coding.
kernel version, desktop component versions, detailed information about hardware and drivers involved, screen size and resolution information,
This all seems legitimate enough, this would be helpful for understanding the hardware their users run on and targeting features or bug fixes.
network device MAC addresses,
Not great but there is an argument for it, they could just grab and send the first 3-4 octets which would give them the info they need on manufacturers without getting uniquely identifiable data that along with some of this other stuff is concerning for fingerprinting.
disk serial numbers,
Okay, what the fuck. Why do they need disk serial numbers? What possible use is there for that. Those are used for warranty claims and could be used as part of uniquely fingerprinting a computer and person. Not cool.
disk partition data,
This is vague enough. I guess one could choose to see this as just info about partitions in use say if there’s also an NTFS partition that looks like a Windows install that would be useful but on the other hand data encompassed within a partition could also nefariously be read as allowing them access to all your data. Partition layout, partition labels, and file systems used on disks available to the system would be a clearer way to put this and erase any doubt.
information about the number of running processes and installed packages, versions of basic packages such as systemd, gcc, bash and PipeWire.
All this is also fine just technical data stuff.
Don’t like it, don’t opt in
Even Debian has popcon
There are lots of benefits for developers to gather telemetry.
Don’t like that? Fork and do your own distro (presumably though you don’t contribute anything to open source, so id expect such people to simply whine and get angry at contributors)
I don’t get why someone would use Manjaro after so many fuckups… If you don’t know what I’m talking about, you’re either too new to Linux or don’t care. Just look for “manjaro certificates” or “manjaro drama” and you’ll find out for yourself.
