- rootfs/usr/local/bin/entrypoint.sh:
1. The "start all services" gate
(`if [ "$START_SERVICES" = "yes" ] || [ -z "$1" ]`) always evaluated
true on a first-run container regardless of $1, because
START_SERVICES is force-set to "yes" whenever no PID file exists yet.
Any command passed to `docker run` — `exec ...`, `sh -c ...`,
`shell`, or an arbitrary program — was swallowed into the
service-start+monitor branch before reaching the `case "$1"`
statement that already handles those subcommands, hanging the
container as a daemon instead of running the given command. Changed
the condition to `if [ -z "$1" ]` so the daemon branch only fires
when no command was given at all.
2. The `*/bin/sh | */bin/bash | bash | sh | shell)` case branch
unconditionally shifted $1 before `__exec_command "$@"` (a bare
`exec "$@"`). For `docker run image sh -c 'cmd'` this turned the
exec into `exec -c cmd` (command not found, exit 127) instead of
`exec sh -c 'cmd'`. Split the branch: real interpreter names
(*/bin/sh, */bin/bash, bash, sh) now pass through unshifted; the
"shell" keyword (not a real interpreter) gets its own branch that
shifts and prepends "sh" to any remaining args, or falls back to a
bare `__exec_command` (exec bash -l) when none remain.
Verified `bash -n` passes. Found and fixed upstream in
dockersrc/go, confirmed identical in this repo's generated
entrypoint.sh, and mechanically applied here with the same patch.
Update volume mount examples and dockerHome variable from
the old /var/lib/srv/$USER/docker layout to /srv/$USER/docker.

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.

from grep -vF /etc/hosts append line; bump version to 202606261500-git

--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
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.

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.
