Notification settings persistence limits in Kali live root sessions

Kali is a rolling release with Xfce as the default desktop and standard freedesktop notification support. The distribution does not ship a distro-specific alerting framework, so alert visibility depends on generic desktop components and user preferences.

In the default live boot the environment is non-persistent, and the primary interactive account is root. This combination creates uncertainty about how notification preferences are stored and whether any tuning to reduce noise survives a reboot.

For a setup that aims for useful alerts without notification noise, the decision point is whether alert tuning is expected to persist in live mode and how root-centric operation affects notification daemon behavior.

Is the Xfce notification daemon configuration expected to be retained across reboots in a stock live session without explicit persistence? Does running the session as root change how per-application notification suppression is applied compared with a multi-user desktop? What documented behavior governs persistence of desktop preferences in live mode?
