Update launch with systemd docs

[enricobenedos]

Hello,

I see that https://questdb.com/docs/deployment/systemd/ questdb.service file seems old due to startup parameters like UseParallelOldGC or missing Dcontainerized param.

Is it possible to update it in order to execute QuestDb with right and best configuration using systemd?

Thanks

Can I do this ??

Hi 👋 It looks like both concerns raised here have since been addressed in the current systemd docs:

• -XX:+UseParallelOldGC (deprecated in JDK 14, removed in JDK 15) was replaced with -XX:+UseParallelGC
• -Dcontainerized=false was added to the ExecStart example

This landed in #453 (2026-05-27), and the current systemd page now reflects it (Java 25, refreshed JVM flags, -Dcontainerized). This one looks safe to close. Thanks!
