Not sure if this will help, but I have a somewhat similar arrangement on a Soekris box running FreeBSD 6.3 booting off a CF device with the need for temporary files that I didn't want to write to the card. I did the following in a startup script:

        mkdir /mem

mdmfs --s 1m --M md1 /mem


this allocates a 1M malloc based disk in the directory /mem. You can then create and delete files there just like a normal file system. Be sure to set the permissions on the directory as needed. If you want to deallocate you can: umount /mem ; mdconfig --d --u 1. Hope this helps,

Hey all;

I'm looking at putting up a machine that would be booting from CF and running net-snmp. Though not directly related to the Soekris product, I'm having a devil of a time trying to figure out where the snmp counters would be. I would want to ramdisk the file(s) or folders where this data is kept rather than constantly writing to the CF device.

Anyone roll this out before?  Any advice?  Thanks!

BTW, the box will be running OpenBSD 4.6
