CumulusMX on Debian

From build 3044 the development baton passed to Mark Crossley. Mark has been responsible for all the Builds since. He has made the code available on GitHub. It is Mark's hope that others will join in this development, but at the very least he welcomes your ideas for future developments (see Cumulus MX Development suggestions).

Regarding running an OS on an SD card - yes it is going to fail at some point. There are a number of options to mitigate that...

Use an SLC SD card - they tolerate orders of magnitude more write cycles.
Use a larger card than you need - spread the writes over more memory cells.
If you have a pi 3 or 4 you can boot from a USB attached SSD drive (I do this), 128 GB USB 3 SSD drives are cheap.
The pi 4 also allows you to fall back to booting from the SD card if the USB drive fails/isn't available. The pi 3 is a one-way journey to USB boot.
Use symbolic links for all the temp files MX creates (realtime files, all *htmtmp etc) to your in-memory RAM drive.
There are nowdays also ”high endurance” rated microsd cards available. For example Kingston makes cards, that are warranted for 3 years 24/7 continuous fullhd video recording, so they should have no problems on typical raspberry usage.
