- pi_shairport: on trixie systemd.pc moved into systemd-dev, so configure found no
unit directory and `make install` died on an empty `install -d` - after it had
already installed the binary. `creates:` then saw the binary and never retried, and
the next tasks failed on the missing unit. Install systemd-dev on trixie, and key
`creates:` on the unit file.
- pi_irserver: with the IRTrans receiver unplugged at boot, irserver exited at once and
stayed failed. Restart it every 10s with no start limit until the device shows up.
- pi_modern_shell_env: get_url sent a conditional request to the oh-my-posh CDN on every
run, so a TLS handshake timeout there failed the whole play with the binary already
installed. Only download it when it is missing.
