Sounds like fun. The idea of being able to run a swap partition in this instance sure does seems nice. In fact the drive I used to test the material for the article I wrote: I forgot to add a swap partition. So I created a swap file with dd . . .it seems to work just fine.
For what it is worth. For my own ideal development environment I prefer to netboot. Simply because I have the added horsepower of my "desktop" system, and the ease of moving things around without having to interact with the BBB directly. Generally this means that single non system files I can copy over on the fly and test, while system directories or files can be done on the fly, but *will* require a reboot. Plus the added benefit of using "non destructive" media. Have fun with your exploration :) On Wed, Jan 8, 2014 at 11:33 AM, Rusty Wright <rusty.wri...@gmail.com>wrote: > Yes, the writes to flash memory is my concern; wearing out the flash > memory.
