Hello I'm no expert and would like to upgrade a Sheevaplug to the latest stable release of Debian. Sheevaplug manufacturer GlobalScale provides two files: Sheeva-Debian7-SW.rar sheevaplug_env.tar.rar http://globalscaletechnologies.com/download/ Should I go ahead with those files or are there better alternatives? Also, to minimize use of the NAND flash memory and the SD card, I'd like to keep /tmp and other temporary files in RAM. Is this OK? Thank you.
