Re: [SOLVED] How to edit the serial number of arch linux?

Ah, we're going to need more information than that.  There is no "serial number of arch linux".  Perhaps you are seeing the serial number of a block device (i.e., drive).  But to know, we'd need to know what you are actually referring to.  Arch linux also doesn't have "Settings" nor "About this System", though I gather your DE or some graphical program you are using does.  So which program is it?

In any case, odds are you cannot change the serial number.  That's the whole point and very definition of a serial number.

So the bigger question is why do you want to change it?

The serial number is functionally useless, so why does it exist?

Re: [SOLVED] How to edit the serial number of arch linux?

I'd guess it might read it from /etc/machine-id which is created by systemd.

Otherwise it might be a hardware serial read from the motherboard, the chassis, the cpu or something else.
lshw might show it and some other serial numbers as well.

On my system, that number is the serial number assigned by Asus to this laptop.  It is also printed on the label.  And shows up in the uEFI menu.

The codes below shows it's the motherboard id.

$ sudo lshw | grep -C 10 SERIALNUMBER

As seen in the bios main page, this is the mobo serial number. In our case, Lenovo SN.

# dmidecode -s baseboard-serial-number

For more details:

dmidecode -s --help
