I had a customer ask the difference between flash, system and nvram?  So far I cannot find this in any manuals.

flash:/ is a read/write partition used to store non-critical (relatively speaking) information. if some demon crashes, the crash information is stored here. custom hotspot pages for advanced hotspot is also stored here. this is also the default ftp root for the on-board ftp server. to use a newer AP300 sensor image, user would copy the new sensor image to flash:/ and use the "wireless | ap-image" command to point to it. system would continue functioning even if flash:/ partition were full. nvram:/ is a read/write partition containing critical information for system to function. this includes startup-config and licenses. although the partition is read/write, user is not allowed to add files here from the cli/gui. system:/ is a virtual partition that exists just to provide read-only access to some of the internal stats that are useful for debugging.
