I think that you will find that the pickle distro already does that. It has the typically<br>'volatile' files in a ram disk (like /var/log , /var/run, etc) for exactly that reason.<br><br>JIM WB6NIL<br><br>> Date: Sun, 20 Mar 2011 10:27:56 -0700<br>> From: phil.n6tct@gmail.com<br>> To: app_rpt-users@ohnosec.org<br>> Subject: [App_rpt-users] Pickle linux, Beagleboard, and MicroSD flash longevity<br>> <br>> I am building a remote, solar-powered, mountaintop repeater based<br>> around the BeagleBoard and app_rpt running the Pickle distribution.<br>> The mountaintop is not vehicle accessible and is a significant hike to<br>> get to -- oh, and it's an eight-hour drive from where I live just to<br>> get to the base of the mountain -- so we'd like to minimize equipment<br>> failures and resulting truck rolls. :-) Two questions for the group:<br>> <br>> 1. Does anyone have any experience with the longevity of the MicroSD<br>> flash memory card used on the Beagleboard with Pickle Linux? Flash<br>> memory has a limited number of write cycles and, although the flash<br>> cards include some wear leveling, I'm wondering what the implications<br>> are for flash card replacement. Obviously, this will depend on how<br>> much writing is being done, but any real-world data, experience, or<br>> anecdotes would be welcome.<br>> <br>> 2. Is there an easy way to set up a ram disk, even a small ram disk (a<br>> few megabytes), under Pickle? The majority of writing we're going to<br>> be doing will be log files, and we have a network connection from the<br>> mountaintop to civilization -- but the network connection is not<br>> guaranteed to be up all the time. If we could write to ram disk and<br>> then copy to civilization when the network is up, that would avoid<br>> having to write to flash at all.<br>> <br>> Thanks!<br>> <br>> Phil, N6TCT<br>> _______________________________________________<br>> App_rpt-users mailing list<br>> App_rpt-users@ohnosec.org<br>> http://ohnosec.org/cgi-bin/mailman/listinfo/app_rpt-users<br> </body>
