[Bug 1790205] Re: systemd journals take up a lot of space, and it's not obvious how much is used, and what the upper limit is.

[Benjamin Bach]

Same issue on Bionic, installed May 15 (2 months ago):

➜  ~ sudo journalctl --disk-usage                                   
Archived and active journals take up 4.1G in the file system.

My logs are definitely clogged with endless JavaScript errors from
gnome-shell. Something I would not expect to slowly consume all disk
space.

What could be helpful feedback for this issue?

Title:
  systemd journals take up a lot of space, and it's not obvious how much
  is used, and what the upper limit is.

Status in systemd:
  New
Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  After running Bionic for 3 months, I had 2.6 GB of journals.

  I would not expect from a normal desktop user that they should have to
  run commands like `sudo journalctl --vacuum-time=10d`.

  I would nominate this command as a sane default to have running at
  each reboot to ensure that logs do not exceed 500 MB:

  sudo journalctl --vacuum-size=500M

  Supposedly, a server should by default retain more logs, so perhaps
  this should be implemented through a configuration package "systemd-
  configuration-desktop" as a dependency of the ubuntu-desktop meta
  package?

  
  ..... as it turns out, it's hard to see how much disk space is used, and what the upper limit is, even when it is set and respected by default.
