P1 PASS: a pre-merge archive (mp0+mp1, confirmed from its own vzdump log)
restore-tests clean on demo-hp with mount_parity ok in 84s. mountParity was
not touched. Limit stated: run with the current agent because the merged one
does not exist until after the STOP; the comparison is archive-vs-its-own-
restore and never consults the host layout, so it carries provided Part 2
honours its constraint not to touch the restore path. Re-run after Part 2.
P2: all three probed variants are mechanically clean — both paths writable,
ONE df figure, dockerd 3/3 reboots, /mnt propagation, and a container's
statfs(/) reporting the merged volume. The task's flagged ordering risk for
V-b did not materialise. They are separated by SCOPING instead:
V-a container sees /mnt = 8.0K but customer data sits inside Docker's
data-root, so clearing /var/lib/docker destroys every local unit
V-b container sees Docker's ENTIRE data-root under /mnt (17.9M on an
empty box), making the bootstrap's own scoping comment false
V-c neutral mount at /var/lib/felhom, both paths binds — breaks neither
V-c was probed because the measurements showed each named variant violates
a different documented invariant. It is offered as a measured option for the
operator, NOT adopted.
Teardown all three layers: 9401/9402/9403 destroyed, 5.19 GB returned, and
the hub registers verified unchanged (5 customers, 4 hosts).
