systemctl disable leaves a link whose unit file is gone, and the manager
keeps asking for the unit. The verb removes only such links in the
account's or the machine's own configuration, on the person's word, and
records each with its reason before removing it (hq issue 332).
systemctl expands *, ? and [ in a unit argument, so reset-failed or stop
of "*" would have acted on every unit. wanted-by called a link dangling on
any stat error, followed a linked .wants anywhere, and missed most of the
manager's load path; it now says each of these, and says nothing names a
unit only of the directories it searched.
mesh/merge-gate fail: builds systemd → ace, g14, novox, shanks; no bus step; a manifest the change touches fails the module check: systemd claims node-serv…
So a leftover unit's trigger is found and its failed record cleared
through the seat, not a shell: wanted-by reads the manager's reverse
dependencies and the enable links naming the unit, saying which dangle.
