compose down destroys hiy-net and evicts running hiy-* containers
from it. compose up recreates the network but leaves those containers
disconnected, making them unreachable until a redeploy.
After compose up, reconnect all running hiy-* containers to hiy-net.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
Without podman system migrate, compose down/up only touches infra
containers. Deployed hiy-* containers are never stopped during a
platform restart so they need no special handling there.
The restart loop stays in boot.sh where it is needed (system reboot
stops all containers).
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
It was added to "pick up subuid/subgid mappings" but that's not what it
does — it migrates container storage after a Podman version upgrade.
Subuid/subgid changes are picked up by restarting the Podman socket,
which the script already does. The only effect of running it was stopping
all containers on every platform start.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
podman system migrate explicitly stops all containers, which overrides
the --restart unless-stopped policy set on deployed apps. After compose
up-d brings the infra stack back, any exited hiy-* container is now
restarted automatically.
Same logic added to boot.sh for the on-boot path.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
- Add infra/boot.sh: lightweight startup (no build) that brings up the
Podman stack — used by the systemd unit on every system boot
- start.sh now installs/refreshes hiy.service (a systemd --user unit)
and enables loginctl linger so it runs without an active login session
After the next `infra/start.sh` run the Pi will automatically restart
the stack after a reboot or power cut.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
podman system migrate was stopping all containers immediately (visible in
the terminal output as "stopped <id>" lines), before the build even began.
Moving it to just before compose down/up means running containers stay
alive for the entire duration of the image build.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
Old behaviour: compose down → long build → compose up
New behaviour: long build (service stays live) → compose down → compose up
Downtime is now limited to the few seconds of the swap instead of the
entire duration of the Rust/image build.

runc (used by Podman) always writes memory.swap.max when initializing the
cgroup v2 memory controller, even without explicit --memory flags. On
Raspberry Pi OS this file is absent because swap accounting is disabled
by default in the kernel, causing every container start to fail with:
openat2 …/memory.swap.max: no such file or directory
start.sh now detects this condition early, patches the kernel cmdline
(cgroup_enable=memory cgroup_memory=1 swapaccount=1) in either
/boot/firmware/cmdline.txt (Pi OS Bookworm) or /boot/cmdline.txt
(older releases), and tells the user to reboot once before continuing.

Two root causes for "invalid argument" when chowning non-root UIDs/GIDs
in image layers:
1. Missing uidmap package: without setuid newuidmap/newgidmap binaries,
Podman can only map a single UID (0 → current user) in the user
namespace. Any layer file owned by gid=42 (shadow) or similar then
has no mapping and lchown returns EINVAL. Now install uidmap if absent.
2. Stale Podman service: a service started before subuid/subgid entries
existed silently keeps the single-UID mapping for its lifetime even
after the entries are added and podman system migrate is run. Now
always kill and restart the service on each start.sh run so it always
reads the current subuid/subgid configuration.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
If entries already existed before this script first ran, _HIY_SUBID_CHANGED
stayed 0 and migrate was skipped, leaving Podman storage out of sync with
the namespace mappings and causing lchown errors on layer extraction.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
Without entries in /etc/subuid and /etc/subgid, Podman cannot map the
UIDs/GIDs present in image layers (e.g. gid 42 for /etc/shadow) into
the user namespace, causing 'lchown: invalid argument' on layer extraction.
Add a 65536-ID range starting at 100000 for the current user if missing,
then run podman system migrate so existing storage is updated.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
Rootless processes cannot bind privileged ports (<1024) by default.
Lower net.ipv4.ip_unprivileged_port_start to 80 at startup, and persist
it to /etc/sysctl.conf so the setting survives reboots.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
Podman rootless unconditionally resets XDG_RUNTIME_DIR to /run/user/<uid>
if that directory exists, overriding any env var we set. Redirecting to
/tmp is therefore ineffective.
Instead, ensure /run/user/<uid> exists and is owned by the current user
(using sudo if needed), mirroring what PAM/logind does for login sessions.
All Podman runtime state (socket, events, netavark) then works correctly.
Remove the now-unnecessary storage.conf/containers.conf writes and the
inline env override on podman system service.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
make build was looking for Makefile in cwd (repo root) instead of infra/.
Use -C "$SCRIPT_DIR" so it always finds infra/Makefile regardless of where
the script is invoked from.
Add -f flag to podman compose up so it finds infra/docker-compose.yml
from any working directory.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
Podman's events engine reads tmp_dir from containers.conf, not from
XDG_RUNTIME_DIR directly. Write both storage.conf and containers.conf
to /tmp/podman-<uid> so no path under /run/user/<uid> is ever used.
Also use `env XDG_RUNTIME_DIR=...` prefix on podman invocation to
override any stale value in the calling shell environment.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
Stop relying on conditional checks. Always point XDG_RUNTIME_DIR and
storage.conf runroot to /tmp/podman-<uid> so Podman never touches
/run/user/<uid>, which requires PAM/logind to create.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
SSH sessions may export XDG_RUNTIME_DIR=/run/user/<uid> even when that
directory doesn't exist or isn't writable. Check writability rather than
emptiness before falling back to /tmp/podman-<uid>.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
Podman uses XDG_RUNTIME_DIR for its RunRoot, events dirs, and default
socket path. Without it pointing to a writable location, podman fails
with 'mkdir /run/user/<uid>: permission denied' even before the socket
is created. Export it to /tmp/podman-<uid> when unset.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
/run/user/<uid> is created by PAM/logind and doesn't exist in non-login
shells. Fall back to /tmp/podman-<uid> when XDG_RUNTIME_DIR is unset so
mkdir always succeeds.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
systemctl --user fails in non-interactive shells (no D-Bus session bus).
podman system service starts the socket directly without systemd/D-Bus,
backgrounding the process and waiting up to 5 s for the socket to appear.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
start.sh now activates the Podman user socket via systemctl --user if it
isn't running yet, then exports DOCKER_HOST and PODMAN_SOCK so that
podman compose (which delegates to the docker-compose plugin) can connect.
docker-compose.yml mounts ${PODMAN_SOCK} into the socat proxy container
at a fixed internal path (/podman.sock), so it works for both rootful
(/run/podman/podman.sock) and rootless (/run/user/<UID>/podman/podman.sock)
without hardcoding the UID.
https://claude.ai/code/session_01FKCW3FDjNFj6jve4niMFXH
start.sh now generates proxy/caddy.json at launch time with Let's Encrypt
automatic HTTPS (HTTP-01 or TLS-ALPN-01 challenge — no Cloudflare needed).
Reads DOMAIN_SUFFIX and ACME_EMAIL from infra/.env before starting.
Added infra/.env.example to document required vars.
start.sh builds via 'make build' (platform auto-detected) then starts
services detached with 'docker compose up -d'.
Makefile gains build/build-<platform> targets that build images without
starting, mirroring the existing up/<platform> targets.
