We got to work with the #systemd team to strengthen Linux 💪

DNS lookups on Linux need to be so fast you don’t notice them, without compromising security. Our team recently helped:

🔧 extend test coverage
🔧 ensure edge cases are covered
🔧 and fix some parser bugs

Hey @systemdUltras #systemd #systemdultras

How to pause a timer during the execution of a service?

Usecase: I have a timer that does a mail-sync every 10 or 15 minutes. I have another timer that does a backup every day at 11. During the run of the backup, I want to pause the mail-sync.

I bet there's a way to properly do this with systemd - I am just not sure what the right way is.

Btw, both of these services are user-services, if that matters.

I'm trying to figure out setting up an email (SMTP) service on my little hosted machines, so I don't need to rely on any particular mail provider.

Which leads me to thinking I really like how #Podman can generate #SystemD units to automatically manage the service containers.

And that has led me to the conclusion I probably should wait for #Debian Trixie release next month, when I can migrate past Podman 4.3.

How do you manage SMTP service for yours, @mike?
