Strange tmpfs mounts for credentials

Gangleri · 2024-07-01 05:24:28

Hi,

Yesterday I wanted to check up my partitions space and df -h spill out this strange table with an unusual amount of mounts:

Filesystem      Size  Used Avail Use% Mounted on
dev             7.7G     0  7.7G   0% /dev
run             7.8G  1.5M  7.8G   1% /run

tmpfs           7.8G   67M  7.7G   1% /dev/shm
tmpfs           7.8G  6.5M  7.8G   1% /tmp
tmpfs           1.0M     0  1.0M   0% /run/credentials/systemd-journald.service

tmpfs           1.6G   64K  1.6G   1% /run/user/1000

systemctl says this about these mounts:

  run-credentials-getty\x40tty1.service.mount                                                                loaded active mounted   /run/credent

  run-credentials-systemd\x2dsysctl.service.mount                                                            loaded active mounted   run-credenti
  run-credentials-systemd\x2dsysusers.service.mount                                                          loaded active mounted   run-credenti
  run-credentials-systemd\x2dtmpfiles\x2dsetup.service.mount                                                 loaded active mounted   run-credenti
  run-credentials-systemd\x2dtmpfiles\x2dsetup\x2ddev.service.mount                                          loaded active mounted   run-credenti
  run-credentials-systemd\x2dtmpfiles\x2dsetup\x2ddev\x2dearly.service.mount                                 loaded active mounted   run-credenti
  run-credentials-systemd\x2dudev\x2dload\x2dcredentials.service.mount                                       loaded active mounted   run-credenti
  run-credentials-systemd\x2dvconsole\x2dsetup.service.mount

Google and the credential services aren't much help to find out what these are... I haven't installed anything recently as well... Please help it bugs me to no end.

Systemd credentials

Please use [code][/code] tags, not "quote" tags. Edit your post in this regard.
Also file a bug at google, it's apaarently broken for you: https://systemd.io/CREDENTIALS/

systemd used to complain about that, apparently now it just makes some up.

I was googling x2djournald and the other weird ones. Alright I'll read the https://systemd.io/CREDENTIALS/ and try to figure out how to fix this.
If successful I'll post it.

Thanks!

What do you want to fix?

Gangleri · 2024-07-01 15:02:27

I was meaning to remove them from being mounted, or place them somewhere else, but I just read more carefully the https://systemd.io/CREDENTIALS/ you provided. And it explicitly says:

For system services the credential directory will be /run/credentials/<unit name>, but hardcoding this path is discouraged, because it does not work for user services.

So I guess they're supposed to be as they are, mounted there...forever disrupting the previously orderly and simple df -l output

df with no arguments is meant to list all file systems. Not file systems some human finds important to them.

You may write a script, that will only list those, which you find relevant.

i thought it pretty annoying too. aliases are great for simple default flags like this. if you don't care about the disk space on any tmpfs, simply add to your bashrc or profile or whatever:

alias df='df -x tmpfs'

luntik20120 · 2024-08-04 22:19:09

but how to disable only systemd garbage? I'd like to see adequate mountpoints like /tmp, /dev/shm, etc.
