/etc/systemd and overrides

Support
1

I placed overrides like this:

[john1@manjaro journald.conf.d]$ ls
10-override-journal.conf  20-override-system.conf
[john1@manjaro journald.conf.d]$ cat ./10-override-journal.conf
[Journal]
MaxRetentionSec=7d
SystemMaxUse=100M
SystemMaxFileSize=15M

[john1@manjaro journald.conf.d]$ cat ./20-override-system.conf
[Manager]
DefaultTimeoutStartSec=30s
DefaultTimeoutStopSec=30s

My questions are:

Is it ok to have two overrides in
/etc/systemd/journald.conf.d/

for system.conf AND journald.conf?

How to force recreation of compile time defaults for journald.conf and system.conf that i deleted because i have this overrides? The header of systemd files tells me: *.conf are recreated if “you delete this file and overrides”

Systemd version:
systemd 252 (252.9-1-manjaro)

I rebooted after deleting systemd.conf and journald.con PLUS corresponding overrides!

Ok, RTFM, but if i ask here i think i circumvent usual pitfalls :slight_smile:

And yes man systemd-system.conf … has all the details but this way i stll don’t see compile time defaults?!

Tipps are welcome!

Hi @JohnML,

AFAIK you have to reload the daemon after any and all changes:

sudo systemctl daemon-reload

Hope this is it!

The overrides for system.conf belong in system.conf.d

No.

The folder journald.conf.d is only for journald.conf. But you can add in this folder ans many override conf files for journald.conf as you want. But not for any other config file.

Why did you deleted these files in the first place? You should not do this. You can also reinstall the systemd package to get them back,

Thanks!

created an extra folder for system.conf overrides and i’ll see what happens!

Too lazy to delete these overrides again to check if they are recreated after an yay -S systemd … i wait and see what happens!

There is no trash bin for root … google: how do i fix that if possible ?

Just learned:

sudo dbus-launch thunar

starts thunar WITH a trash bin, so i deleted all folders with overrides then i executed yay -S systemd … and the compile time system.conf and journald.conf are back !

It’s dbus not debus
