# Upgrading systemd runs its post_upgrade scriptlet mid-transaction, which
# reexecs both the system manager and every user manager. A pacman running
# inside a user-session scope can be SIGKILLed by that reexec, abandoning the
# transaction halfway. Registering the transaction as a PID 1 scope keeps it
# out of the user manager's cgroups entirely, and system scopes survive the
# system manager's own reexec.
