jason.woltje 00d4cc1f69 stack: several Mosaic Stack instances on one host (row 190, #1688)
Squash of Darkwing's 176a6bf4b..df65a3d4c on origin/darkwing/row190-r3,
the 25 manifest paths, build-r3.patch efe898c2, manifest cc0ea9e8
(Filbert approve round 3, comment 29713). Design revision 3 in
agents/darkwing/work/queue-190/DESIGN.md. Gate on base d0bbc5c1c with
the patch: 15 package suites 2664 pass 0 fail, 10 scripts/test-*.sh
suites 429 pass 0 fail (plus 156 node tests in the queue suite).
Refactor moved to 99a406ed3 since, a window record touching no manifest
path. Mutants 20 of 20 killed (BUILD.md, round 3). No live change: the
stack runs from copy 4429a104f until a re-pin.

# A supervised run first clears a lock left by a crash or a reboot, and
# refuses with exit 3 while STOP is present or the binding is held. Exit 3
# is never retried: the brake belongs to the operator. This happens inside
# the main process on purpose: systemd honours RestartPreventExitStatus only
# for the main process, so a refusing ExecStartPre would loop.

# `systemctl --user reload` re-reads the binding in place (channels, users,
