Package: dpkg
Version: 1.22.6
Severity: normal
Dear Debian folks,
Trying to decrease the boot time of a desktop system (pressing the power
button to GDM login screen), I noticed `dpkg-db-backup.service` in the
hotpath:
May 19 06:18:53.272044 abreu systemd[1]: Started

GNOME Display Manager.
It’d be great if this could be moved out the hot path, for example, by
running it at least ten(?) minutes after the system has been started.
Kind regards,
Paul
