__exec_command was using ${arg:-} which only captured the first element
of the args array, then ran it through "$shell" $pre_exec "$cmdExec"
which effectively discarded everything after $1.
Running `docker run image sh -c 'go build ...'` would:
1. Set arg=("sh" "-c" "go build ...")
2. Set cmdExec="sh" (only first element)
3. Run bash --login -c "sh" (dropping -c and the actual command)
This broke any Makefile GO_DOCKER pattern that relied on passing multi-arg
commands. Simplified to just `exec "$@"` which passes all args through.

__setup_mta calls __find_replace on /etc/ssmtp/revaliases which returns
1 when the symlink it creates is broken. With set -o pipefail active the
non-zero return kills the entire entrypoint before any command can run.
ssmtp is not installed in this image and email delivery is not a feature
of the Rust developer image, so the MTA setup failure is irrelevant.
Guard the call with || true so initialization continues regardless.
- rootfs/usr/local/bin/entrypoint.sh: __setup_mta || true (non-fatal)
rootfs/usr/local/bin/entrypoint.sh
The grep -vF line that appends /usr/local/etc/hosts entries had a
duplicate 2>/dev/null redirect after the append operator, which is
a no-op but clutters the script. Synced from template.
- rootfs/usr/local/bin/entrypoint.sh: remove duplicate 2>/dev/null
from grep -vF /etc/hosts append line; bump version to 202606261500-git

Stale copies called __initialize_default_templates, __initialize_config_dir,
and __initialize_data_dir which are not in the old functions library,
causing container startup failures. Replaced with current template
versions (202606041210-git) which no longer call those missing functions.
- rootfs/usr/local/bin/entrypoint.sh: update to current template

--domainname on the container sets the kernel domainname, which c-ares
uses to infer a search domain even when /etc/resolv.conf has no search
line. This caused c-ares to query github.com.casjay.work AAAA and get
the host's own IPv6 address, routing all outbound HTTPS to the local
nginx instead of the real server.
Adding 'search .' and 'options ndots:0' explicitly disables search
domain inference regardless of the kernel domainname setting.
- rootfs/usr/local/etc/resolv.conf: add search . and options ndots:0
rootfs/usr/local/etc/resolv.conf
Hosts with a search domain cause containers to inherit it. When the
zone has a wildcard AAAA record, public hostnames resolve to the host's
own IPv6 address instead of the real server, breaking all outbound
HTTPS and DNS from inside the container.
The entrypoint already has a hook: if /usr/local/etc/resolv.conf
exists it replaces /etc/resolv.conf at container startup. Ship a
clean resolv.conf with Cloudflare + Google DNS and no search domain
so container DNS is always correct regardless of host configuration.
- rootfs/usr/local/etc/resolv.conf: new file — clean DNS, no search domain
rootfs/usr/local/etc/resolv.conf
Synced from casjay-dotfiles templates. Updated functions now check
for existence before copying template-files directories, skipping
gracefully when they are absent.

Install latest stable Rust at build time via rustup-init with SHA256
verification. Add 30 cross-compile targets, cargo-binstall, and a
comprehensive set of cargo development tools. Match the official
rust:alpine env-var convention (RUSTUP_HOME / CARGO_HOME) and declare
those paths as Docker VOLUMEs. Add the Go-image pattern: rust-workflow
runs automatically when the container is invoked with no args, while
explicit commands pass through unchanged. Copy language-agnostic
healthcheck, copy, and symlink utilities from the Go image.
- Dockerfile: WORKDIR /app in final stage; add RUSTUP_HOME, CARGO_HOME,
RUSTUP_TOOLCHAIN ENV vars; extend VOLUME to include cargo and rustup paths
- rootfs/root/docker/setup/05-custom.sh: full Rust toolchain install —
build deps (build-base musl-dev clang lld cmake openssl-dev), SHA256-
verified rustup-init, stable toolchain with rust-src/rust-analyzer/
llvm-tools-preview, 30 cross-compile targets, cargo-binstall bootstrap,
cargo tool suite via binstall, cross-linker config.toml, /usr/local/bin
symlinks, ~/.cargo and ~/.rustup home symlinks, /etc/profile.d/rust.sh
- rootfs/usr/local/bin/rust-workflow: default workflow script —
fmt --check → clippy -D warnings → test --all → build --release;
honours CARGO_WORKDIR and CARGO_BUILD_TARGET env vars
- rootfs/usr/local/bin/entrypoint.sh: __no_exit guarded by $# -eq 0 in
START_SERVICES block; * catch-all now calls rust-workflow on no args
- rootfs/usr/local/bin/healthcheck: copied from Go image (HTTP/TCP/
process/file health probe)
- rootfs/usr/local/bin/copy: copied from Go image (recursive copy utility)
- rootfs/usr/local/bin/symlink: copied from Go image (symlink utility)

Update the embedded entrypoint copies in rootfs/ to match the
upstream template change. Internal state files renamed to dotfiles
so they're not matched by `/run/*.pid` cleanup globs:
- /run/init.d/entrypoint.pid -> /run/.entrypoint.pid
- /run/no_exit.pid -> /run/.no_exit.pid
- /run/backup.pid -> /run/.backup.pid
- /run/__start_init_scripts.pid -> /run/.start_init_scripts.pid
Per-service PIDs in /run/init.d/ are unchanged.
