The three roots are independently relocatable, and the failures that matter are
the ones where only ONE of them moves: paths are baked into root-owned helpers,
the systemd unit and the CLI wrapper at install time, so anything that resolves
a root at runtime instead works on a default install and points at the wrong
disk on a relocated one. Testing "all default" or "all moved" misses that.
scripts/dev/lp-testdisk loopback ext4 disks — a real superblock, its own
st_dev and free space, thrown away between runs
scripts/dev/lp-install-matrix installs across the four root combinations and
checks each landed on the intended DEVICE, that
the helpers were baked (no __PLACEHOLDER__ left)
and that the WebUI answers
First thing the harness turned up: lp-shot hardcoded /libreportal-containers for
both the compose file it reads the published port from and the .auth.json it
signs a session with. On an install whose app data is on another disk it fell
back to a default port and a missing auth file — which looks exactly like a
WebUI that failed to boot. It now reads the baked LP_CONTAINERS_DIR back out of
the CLI wrapper.

# Why loopback rather than a spare partition: the code paths that matter care
|
|
# that a location sits on a DIFFERENT filesystem — appDir resolution, the
|
|
# storage registry's device numbers, `st_dev` comparisons in the installer's
|
|
# disk picker, and app-adopt's same-device mv vs cross-device copy. A loop
|
|
# device gives all of that with a real ext4 superblock, its own st_dev and its
|
|
# own free-space figures, and can be thrown away between runs.
|
|
#
|
|
# Sparse-allocated, so a 30G disk costs what is written to it, not 30G.
