zram for swap, /tmp and logs
Replace the swapfile with compressed RAM block devices via zram-generator to cut SD-card writes — Chromium gets a little snappier.
What it takes
- Software only
- Config change
Difficulty 1 of 3 — easy.
Details
blaknite's zram-generator config (July 2024) creates four devices on the Bookworm image: a 1,024 MB swap plus /var/compressed (256 MB), /var/tmp (256 MB) and /var/log (128 MB) as mounted zram filesystems, using bind mounts to keep the existing directory contents and the 1777 permission trick for tmp-style directories. The point is fewer writes to the SD card and faster temporary storage; the reported effect is a slightly snappier Chromium and no stability problems.
It is a systemd configuration exercise — get the permissions and the bind-mount migration right or logs and temp files go missing.

Run a Meshtastic node on the console itself: meshtasticd drives the AIO's SX1262 over SPI, with the graphical MUI, the web UI or the Contact TUI client on top.
On Rex's images a single apt install gives you SDR++ for the AIO's RTL-SDR or a USB dongle; his AIO package adds the sdrpp-brown fork.
Rex's ClockworkPi-RetroPie image (Pi-Gen, EmulationStation, RetroArch) is the working answer; the Debian install and gamepad threads fill in the rest.
jutleys booted a prepared Windows 95 disk image in RetroArch's DOSBox-X core with working mouse buttons; plain DOSBox on the A-06 needs output=opengl to behave.
Two receivers, two recipes: the 4G card's GNSS via AT+CGPS on /dev/ttyUSB3, or the AIO's GPS on the serial port (/dev/ttyS0 CM4, /dev/ttyAMA0 CM5) at 9600 baud.
The AIO's PCF85063A keeps time off-grid once the right overlay is in config.txt — and on a CM5 the built-in fake RTC has to be switched off first.
