Home folder in terminal: strange "name"

if i open a terminal i see:

john1@5b1bb8ab-8e66-4ff7-847f-30aae5957f6f:~$ blkid | grep -i 5b1bb8ab-8e66-4ff7-847f-30aae5957f6f

It is NOT a UUID, but?

It’s the hostname, not a block device uuid.
Why your hostname is set thus is another question.

What gives you hostnamectl ? There I do see two ID’s too. But both without dash’s.

Was it after an update or a new installation or just out of the blue?

Strange: just rebooted and now it is “normal”

… and it is not part of hostnamectl !

I am new to fedora but i think i wondered before over that strange naming …

We’ll see what happens now, thanks for the answers!

For hostnamectl, see

ohn1@fedora:~$ hostnamectl

What I can see is in the “transient” (vorübergehender) Hostname in your hostnamectl.
You can change the hostname with:

*hostnamectl --help

  status                 Show current hostname settings
  hostname [NAME]        Get/set system hostname 

This should set a static host name and keep it.

Fedora is the default name when you do a Installation. To better distinguish my diverse installations I do a hostname change after installation including a pattern who unifies the machine (ex. dell-fe39).
