now this is the sticky part. imagine this system out in the field, where you need to make an update to something in the initrd in the root filesystem. one technique would be to, of couse, download an entirely new initrd.gz and reflash (hoping no one pulls the plug as you're doing it), as you describe above. what about sacrificing space and having an uncompressed root filesystem in flash? and, if that's possible, would one mount it read-only from flash (speed?), or just copy it into RAM and mount that every time? if all this is covered somewhere, a URL would be fine, thanks. rday
