Doesn't look like that to me, at least not out of the box. "df" shows: root@peekskill:/var/log# df -h Filesystem Size Used Avail Use% Mounted on /dev/mmcblk0p2 3.6G 1.4G 2.0G 41% / none 244M 180K 244M 1% /dev none 245M 0 245M 0% /dev/shm none 245M 40K 245M 1% /var/run none 245M 0 245M 0% /var/lock none 245M 0 245M 0% /lib/init/rw So yes, /var/run and /var/lock appear to be something special (though not clear to me they are ram disks), but /var/log (which is where most of the writing takes place) is definitely on the micro-sd card: root@peekskill:/# cd /var/log/asterisk root@peekskill:/var/log/asterisk# df -h .

I think that you will find that the pickle distro already does that. It has the typically 'volatile' files in a ram disk (like /var/log , /var/run, etc) for exactly that reason.

I am building a remote, solar-powered, mountaintop repeater based around the BeagleBoard and app_rpt running the Pickle distribution. The mountaintop is not vehicle accessible and is a significant hike to get to -- oh, and it's an eight-hour drive from where I live just to get to the base of the mountain -- so we'd like to minimize equipment failures and resulting truck rolls. :-) Two questions for the group:

1. Does anyone have any experience with the longevity of the MicroSD flash memory card used on the Beagleboard with Pickle Linux? Flash memory has a limited number of write cycles and, although the flash cards include some wear leveling, I'm wondering what the implications are for flash card replacement. Obviously, this will depend on how much writing is being done, but any real-world data, experience, or anecdotes would be welcome.

2. Is there an easy way to set up a ram disk, even a small ram disk (a few megabytes), under Pickle? The majority of writing we're going to be doing will be log files, and we have a network connection from the mountaintop to civilization -- but the network connection is not guaranteed to be up all the time. If we could write to ram disk and then copy to civilization when the network is up, that would avoid having to write to flash at all.

Thanks!

there should be an announce about availability shortly From: tom.km5vy@gmail.com Date: Sun, 20 Mar 2011 18:29:25 -0600 To: phil.n6tct@gmail.com CC: app_rpt-users@ohnosec.org Subject: Re: [App_rpt-users] Pickle linux, Beagleboard, and MicroSD flash longevity On Sun, Mar 20, 2011 at 11:27, Phil N6TCT <phil.n6tct@gmail.com> wrote: I am building a remote, solar-powered, mountaintop repeater based around the BeagleBoard and app_rpt running the Pickle distribution. Are you using a LOX board for this, or are you using USB dongles? I'm keen to find out when LOX boards will be available for sale, as the local repeater club is looking at a big asterisk project that might be a good use for the Beagle and Lox (and capers and onions and tomato?) solution. -- Tom Russo KM5VY SAR502 DM64ux http://www.swcp.com/~russo/ Tijeras, NM QRPL#1592 K2#398 SOC#236 http://kevan.org/brain.cgi?DDTNM "The truth will set you free, but first it will piss you off." _______________________________________________ App_rpt-users mailing list App_rpt-users@ohnosec.org http://ohnosec.org/cgi-bin/mailman/listinfo/app_rpt-users
