- 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.
The xorg Dockerfile was trying to use casjaysdev/xorg:latest as its base
image, but that image doesn't exist yet — it's what we're building.
Changed to use official debian:bookworm as the base since the pkmgr script
uses apt/apt-get and the packages (xorg, x11-apps) are Debian packages.

Dockerfile
__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 this image, so the MTA setup failure is irrelevant. Guard the call
with || true so initialization continues regardless.
