Debian packages that turn a Raspberry Pi running Raspberry Pi OS Lite (Trixie) into a Pi Hero device:
pihero (boot configuration, MOTD, watchdog) and pihero-avahi (the device in Finder with a model icon).
The packages, their source, and the device files that install them on first boot live at
github.com/bkahlert/pihero.
The flat repository at /pihero/apt is signed with the key whose fingerprint is
DE60 9D7F F5BE 430D AC8C C807 081F 70E6 A077 DF7A. Device files embed it; on an existing system:
