[tahoe-dev] Precise Puppy (linux) tahoe-lafs 1.10.0 initial report

[Anders Genell]

Hi again, sorry for replying so late...

The Pis used for storage nodes are in general not used for anything else, and we try to keep X turned off to save resources. You can also lower the amount of RAM reserved for the GPU to a minimal 16 Mb in the config.txt file in the Pi boot partition. 

Also, some of our Pis krashed when stressed, e.g. by uploading a bunch of very large files, until the SD card was replaced by a Sandisk SDSDX-016G-X46. The Pi is notoriously sensitive about what card is being used. 

Finally, if lack of memory is limiting performance, it is possible to set up a swap partition on the Pi. It will slow things down horribly, of course, but may just get the job done. 

Regards,
Anders

My RPi consistently simply dies during the trial - no errors, it just... stops, but based on your feedback, I'll continue.

At this point, I'm targetting something more like the old terminal/3270/DOS menus and/or wizards - simple walkthroughs with questions to answer that can be used to create the files for an entire grid, or add to an existing grid's files, hopefully with some manner of "wrapper" (Tor, I2P, OpenVPN) capabilities available as well.
