[systemd-devel] How to disable systemd snapshot

[Rock Lee]

Hi, there:
From the security concern, I need to disable systemd snapshot. I
searched Google, but found nothing. Can anybody give me a hint?

If you're referring to the `systemctl snapshot` feature which remembers
currently active services – it was removed several releases ago, and before
that it was only usable by root.

Systemd does not have any other "snapshotting" features (as far as I can
remember), except maybe some distro-specific btrfs services.

Indeed, there is no "systemctl snapshot" in the recent sytemd source
code. I am using yocto which with systemd 216, that's quite old. Do
you know why "systemctl snapshot" was removed?

It wasn't very useful.
